Univolt Fuses

[Keyholeren]

I have a '67 Safari with what I presume to be the original univolt. It was fine this morning, but suddenly quit. I did find an internal fuse and replaced it. Everytime I power up (city power) the new fuse blows. Any ideas?

Thanks

If you have the original Univolt, I believe you only have two, 40 amp fuses on the battery leads. Please reply if you have more.

If this IS the case, it is possible that you have connected your battery backwards.

I see three probabilities:
1- The battery is connected backwards, as was mentioned in the previous post. Check polarity and go from there.
2- You have a serious short in the low voltage system. Check your lights, fans, motors, etc, and repair as needed. Especially look at the wiring between the Univolt and the battery.
3- The Univolt is dead. Long live the Univolt.

I do have a picture of the outside of the converter but I'm not sure how to add it to the thread. The opinion seems to be that there is a short on the 12v side some where. I'll start buy pulling the fuses as suggested to the various circuits.

Thanks.
