no power

Mike · 08-18-2002, 11:00 AM

I have a 1970 27ft overlander I just purchased. I have it parked in my driveway and pluged into my house everything was working fine ,but for some reason I have lost power. I have checked circuit breakers and fuses nothing triped in house or trailer. Any ideas?

Hi Mike,
Check and see if you lost 12V power or 110V power.
A lot of components run on 12V, so if they don't work, then youlost converted 12V power.
If the 110V outlets don't work, then you lost power altogether, I guess.
If you lost 12V only, then probably it's a bad fuse or a loose connection.
My connection at the Univolt and battery were all loose, some ready to fall off.
Good luck!

Check your fuse panel closely and pull the large fuses that work straight from your battery. They might be loose. Also check your univolt for any power output. Unplugged, are you saying that there is no 12 v. power either?

Yes, unplugged I have no power but I initially thought that when I hooked up my 120 line that would override my battery . The fuses don't look like they're blown but I'm going to start there and replace every one.

Thanks for your help.

Mike,

The 12 VDC and 120VAC systems only come together at the univolt. Do you have any 120VAC power? AC Blower or a household style lamp that works in the trailer?

On the 12 VDC Side have you checked for a battery, or checked the battery itself? A Missing battery will cause a univolt to fail if used with no load connected to it for a while.

We are here to help, but need more info as to the symptoms. David is now an expert after his troubles.

So let us know what you find and we will give you our educated guesses!

Mike,
Keep posting what you find after you get suggestions from the forum. As several of the members told me earlier, you will find the problem sooner or later.

To All Who have offered suggestions:
Thanks, . I did try plugging in a lamp and it worked. I am still looking for a source for the fuses. Radio Shack and Lowes' didn't have them. My overhead lights and fan and radio do not work and the panel light doesnt' work either. Air C works. I initially thought that plugging into 120 would run everything. When Ithe power went out I was in the middle of ripping out my black water box that was totally rusted out so I'm in the middle of 2 projects here.

Thanks again for all who have posted and I will try to keep you all updated.

MIke,

If the 120 VAC works, but no 12 VDC works then you have narrowed it down to the battery, the univolt, or the fuses. Find the fuse panel and check the main 50 AMP fuses first. You may need to go to an RV dealer to find replacements. They can run 5 bucks each, but they are by far the cheapest fix on the electrical system. There are usally 2 fuses, both the positive and negative sides are fused.

Hey Thanks Brett. I'm learning as I go along here. I looked again at the 60 amp and it looks like it may be the culprit. Now I will be better equipped to "see" my bathroom floor problems.

Mike,
Both our trailers should use two 50 amp fuses which are bigger than the regular Buss fuses we have come to know. I also checked Lowes and a couple hardware stores and did not find a replacement. I am going to check one more local hardware store then bite the bullet and try a local RV place in my home town. If no go, I will go to the big city of Nashville and check a couple RV places there. You are starting to narrow your problem down. Good luck.

Good Luck!

I may start checking on the internet. Saves time and gas (at 1.35 gal)
