Gees he let me down! But as you are all guys I'm sure you will understand.

It is playoff time and the Leafs have made it to the second round!!!

He is off tomorrow and we will get to those tests in the morning and post the results sometime tomorrow.

Stay tuned Tom, Smily and Brett have not forgot about you and all your help!!!

Well the playoffs are over for the Leaf's

And to get a bit of a kick start (or interest in the electrical system again) I thought I would buy a new extension cord - something on the technical side I can handle - and after the trouncing I got on the Towing Thread I think I will steer clear of there too!

So Smily and Tom you are right on the Polarity - turns out that the cord we were using was the culprit and not the cords with the trailer.

Still have the issue of no 12V when Battery not hooked up but shorepower is.

Smily - what you said makes some sense to me - so I will get into the back and check out what size fuses should be in the empty slots - pick them up and let Peter check out the rest of the system when he get's home - that is of course if it is not pouring with RAIN - cause that is the only thing that stops him now (although I did see the ball game on tonight.)

Quote:
The Univolt should have all fuse slots filled. The main fuses or larger ones are for two sources, converted power and battery power.

I think the missing fuse is your problem as for lack of 12 volts with no battery but connected to shore power.
Tom - Peter will go back to doing all the meter tests this weekend - so hopefully I can have some kind of report back and close up this thread. Just have to sort out the above issue now and we are set - well at least on the electrical side.

Still have some plumbing and LP issues to take care of but they are much easier than the electrical

Chuck you don't know how close you were boyoh . Marvin our main A/S main (okay so he is the only guy up here we know that has tinkered with them )

He also said the kitchen sink light - but then we went one step further and tried it with the "salon" light it is in the isle way just before the dinette but not over the kitchen sink....yes one more mystery solved - thanks Chuck for getting us on the right track.

Back to the Univolt problems. We have solved most issues - thanks to the tests ideas from you guys.

However we have loaded up the Univolt empty slots with all the correct fuses, she hums like a baby and puts out the perfect AC through all the outlets, fridge works on AC (A/C still not tried yet). But when we come to all the 12V systems they are not running through the univolt - no readings dead as a piece of wood.

So I guess it could be one of two things - a) as another thread mentioned we may have a ground short on the Univolt between the battery or b) looks like a few of you fellows might be right - may need to do some work on the capacitors??? or replace it. A project for another day... and probably a new thread when it comes time.

In the mean time we will be sure and pack our battery charger and if boondocking may have to drive around a few blocks - as our charging line works like a charm.

I know there are some great threads on repairing the univolt so we will read up and post any questions when ready.

Peter will replace the ground wire on the off chance that is the culprit if so we will let you know if not stay tuned or keep your eyes out for the lost Univolt souls

Thanks again all your help has been invaluable!!!
(PS gee who does not say thankyou on this forum )

not that it really matters, but the univolt doesn't put out "ac". just "dc". The ac comes in through the umbilical cord to a ciruit breaker box, just like in the house. from there, wires run directly to the a/c outlets...and to the univolt as well..but it then takes that a/c and converts it to dc to power the 12v lights/outlets/appliances. and if there's anything left, it sends it to the battery for re-charging.

My trailer has 2 a/c circuits; one is dedicated to the Air Conditioner (I almost typed "ac"...doh! too confusing), the other is for "everything else".

that's what I meant - have the "a" on my mind 24/7.

However Chuck - our plugs are DC only not 12 volt - as the 12 volt items all work but run off the battery. As mentioned somewhere way up in the thread our original problem other than running the battery down was that when we unhook the battery and are still pluged into shore power the UV still hums and works the plugs and fride but no over head lights/fans or any 12V items.

That is where we think we might have a short - but have to check it out this week sometime - few other little projects. And if not a short then UV is Toast and if we can not repair it will go on the pile with the Hot Water Tank, On demand pump and filter, Toilet - and eventually the awning We new we would not come out of this unscaved...

Ok, this is not making sense to me, but your trailer is different than mine, although it shouldn't be tooooo much different...only 4 years older...but anyway, there are 2 kinds of electrical outlets in my trailer. 5 of them are 110v/AC. These are the ones that look and work just like the outlets in my house. There are also 3 12v DC outlets. these look like the cigarette lighter in my car. I think you might be confusing "AC" and "DC". 110v house systems (on this continent, anyway) are 110v AC; automotive electrical systems are typically 12v DC. So how can you have DC plugs that aren't "12v"?

The 110vAC outlets do not get their power from the univolt. the electricity bypasses the univolt completely, going from the source (shore plug) through the circuit breaker box, and from there, directly to the outlets. I believe you said that the "dc outlets work when plugged in to shore power"...since there probably are DC outlets in your trailer, and we're probably all assuming that there are, this is confusing people. What you're saying is that "some 12v stuff works, and some doesn't, when plugged into shore power". I'm thinking that this is not the message that you are trying to convey. am I correct?

so I'm still thinking that your univolt is not putting out any 12v, and this should be really easy to test. disconnect the battery, plug the trailer into shore power, and put a voltmeter on the 12v side, and see what you've got.

Nope not much different - just you and I got our wires crossed

Okay I have 4 AC and 1DC

However I think I was right in my first post indicating that when plugged into shore power with battery disconnected my AC plugs all work and so does the AC operation of the Fridge. But on the otherside the univolt does not seem to be converting the AC to DC in order to run the lights, fans, water pump (and the one DC outlet I did not mention above). But when we hook up the battery all our DC systems work fine.

We have done the test and we get nothing from the Univolt 12V side - so as previously indicated we either have a short in that wire or terminal or we have a pooched UV.

I said DC in this sentence cause you just finished telling me that they were not AC but in fact DC

Well that is great I just learned something new again. But we have been told and I have read by many here that you don't need a battery for the UV to convert the 110AC to 12V DC so that you can operate your 12V systems - it also says this in the Owners manual - but ours does not work -even though she humms quite a nice tune....

Nope don't think so all our 12V Stuff works off the battery but none of it works when the battery is unhooked but the shore power is pluged in and the univolt is running.

Yep did that and like I said dead as a piece of wood.

So are we on the same page???? This was fun - was there not a group called ACDC or something like that

yep. ok. your univolt is broken.

the electrical guru's here all recommend the intellipower w/ the charge-wizzard, if you're going to replace.

one of the members sells them, I think...try "www.bestconverter.com"


Interesting thing about your custom electrical panel. you've got 4 ac circuits...mine only has 2. wonder if that's "factory", or some sort of upgrade. (and if so, why?).

Hi Chuck;

As far as we can tell she is pretty much original except for a few things here and there - such as a new dump valve in 1992. We have hooked up with another couple who just purchased a 1969 GlobeTrotter from the original owner. They have exactly the same set up in the back as we do - so I don't think it is custom.

The 69 year was a funny one - they built it in 68 but I think they took the end stock of 68's parts and matched them with parts from the new 70's coming in.

Nevertheless she is a great little trailer - but boy are those $$$$'s adding up. But then nothing in comparison to a new one - or as I have said before those poor people doing a complete rip out.

Will check out your suggestion - but another....for now....we will tote along an extra battery and our battery charger -it will get us by.
