Univolt????help

[Happycampers]

Hello, I am having a problem with my 12 volt and don't know if it might be the univolt. All of the fuses have 12.2 volts and nothing works, when I plug into 110 everything works and the univolt hums and the battery reads 12.3 volts. What is wrong? Thaks for your help. Marvin

there may be one more fuse you are overlooking.

the negitive lead has a fuse also.

you may want to remove the fuses and use your volt meter set to "ohms" or the omega symbol and check for zero ohms on each fuse.

that way you can be 100 percent sure it is something else!

Marvin,
Make sure your negative battery cable is not full of corrosion.... run a new ground to test with such as a jumper cable on negative (-battery) to chassis.

Check your battery..it should read higher than that if it's properly charged.`
btw, just what kind of battery do you have?? I hope not an "Auto" battery`!

Hi, I found the problem this morning, the ground had been spliced way behind the oven and it was corroded badly. Everything works great now. Thanks ot everyone for all the help. Marvin
