I did some current measurments before and after my Univolt replacement. Before, the old Univolt required 5 to 6 amps at 120 volts, depending on battery condition. It never went below 5 amps.

With the new Intellicharger, it draws about .3 amps with a fully charged battery. Have not had a chance to draw the battery down, but now it looks like I'll save some coin on my electric bill, as well as generator fuel when boondocking!

While we're at it, Pick, when you use your gen when boondocking, do you attach the gen directly to the battery or just plug your coach into it and let the intellipower charge them as it runs.

Thanks - Pat.

I would plug the shore power cord into the generator (using an adapter if needed) and let it power the converter/ charger.

Identical Problem

It seems that the uni-volt will keep the lights on and operate everything when I take the battery out of the circuit, but once I put it back in we have the same problem. Could it be a bad battery already?

I've been searching these threads for someone who described the issue I'm having with the electrical system in my 1970 Caravel. My lights dim and surge when I am hooked up to shore power and the battery is connected. I also hear the clicking in the univolt that you describe. If the battery is disconnected the power is full and consistent. If I am running solely on the battery, power is consistent as well.

What was the solution to your problem? I was prepared to pull out the univolt and take it to someone who said it was a bad converter, but I thought I would try the forum first. Any insight?

Thanks

If your converter is original, it is a bad converter by date and design. Just the facts but some will play with them for the nostalgic charge and that is fine, kinda cool but not practical. Sort of like going to the fair and watching the old single cylinder engines on display, facinating. Anyway, take that guy up on his offer. I'll buy it if you can show me why you wish you didn't upgrade.

As one who has designed and installed dozens of complicated electrical, battery, and charging systems in expensive yachts, i have tossed my three cents worth in some of these threads about batterys and such; But i remember what a naval engineer said to me: " you can't have to many batterys".

Smile Hi All,

I finaly steped up and bought a 60 Amp Intelli-Power Charger.
My question is: There are tree wires under the front couch.
One is white,one is Black is very small and a ground wire which is a copper ground wire. The red wire is no problem but the white and black drive me nuts. Which is the ground for the battery?
I have a schematic for my 1985 Sov. But it does not show how the hook up is for the charger.
Please write or send directly to me at rdworian@comcast.net
Thank you for any help.
Russell in Sunny and cool Tucson Az.

Howdy,
Their are two configurations to my DC wiring. The normal Red being positve Black being negative. The other is Black being positve and White being negative. Be careful and check polarity or continuity with an ohm meter if you are ever confused which is which or where things go before energizing. Sure wish I had some time to work on my wiring some more. If you do not already have one, a nice distribution block by your new charger sure makes the install clean Good Luck and have fun!!

The disconnect I used is pictured, purchased at a marine store.

Another solution is a plug in heavy duty timer for appliances have the univolt run like 2 hours a day to keep batteries full but not over charge them . I used this method before I got my 9100 . It did good job .

Question for Mrcrowley...

Reading these messages over the past week or so, I'm convinced that a decent upgrade for the Univolt is the INTELI-POWER. I just bought a 9200 (45amp) for my '77. There were no instructions in the box for installation!

Judging by the connection, it looks like a straight forward install. However, the Univolt appears to be wired with multiple DC outputs.

Do you know where I can get install instructions? What did you do with your Univolt after upgrading with your 9100?

Thanks!

The original univolt has the DC distribution board attached to it. You must either reuse this board or install a new 12 volt panel. I installed the same unit in my 75 and the installation instructions are very basic. Screw it to the floor, attach the 12 volt output lines and plug it into 120 volts.

Lumatic did a nice modification by mounting the new unit into the shell of the old univolt.

More on univolt and shore power

My 1970 31' Airstream is my hunting camper from November through the end of February. I have power and water at camp this year (only had power last several years)!
My old battery was dry as a bone when I pulled it out in March.
I replaced it with a new deep cycle.
After reading and re-reading this topic thread, is it OK to leave the 120 volt shore power plugged in, but disconnect the battery when the trailor is not in use (leaving 120 for the refridgerator)?
I have not measured the voltage output of the univolt - is it adjustable?
many thanks,
Charles Rahm
