electrical problems

[mattie]

Hi there, We just bought a 1969 tradewind and until two days ago everything electrical was working good. Then the 40 amp fuses went. Does anyone know if you can get them anywhere or if we have to get new fuse box and redo it all. We are new to the airstream but really excited to fix it up. Any advice will be great!

Welcome to the forums!
You can get those fuses at many different places. Out-of-Door-Mart is just one. To blow a 40amp fuse, you mush have a short. I would use a meter to check for shorts before I put another fuse in.

40 is a big fuse. AC or DC. Someone may have put that in rather than fix a problem.

There may be two of those large fuses in your unit. One on the (+) side of the converter, and one on the (-) side. The (-) one is sometimes hard to find and is over looked. You can not look at them and see if they are bad. You have to meter them for continuity, and they can be very hard to get out of their single fuse, fuse holder. They have to be metered outside of the fuse holder.

Here are links to those large fuses. Thanks for the plug Richard.

The big 40 amp glass fuses can be found at audio shops. I may have an extra if you can't. The smaller (standard 70s auto size) are scarecer than teats on a boar hog. You can get up to 35 amp AGC fuses at a lot of auto stores which will usually work. You can also get a 40 amp auto resetting breaker which fits into the fuse holder. Only problem is it will keep resetting itself which defeats the main purpose of a fuse, to burn out and break the circuit if there is an electrical problem somewhere in the system.
