It's 30 amp with a 15 amp fuse. Thanks for your help. [Reply]   [No Email]

I hope I'm wrong, but I think that switch is meant to use with a cut out and not a voltage regulator. On those, the fused end is the OUTPUT to the lights, not input. You only get lights when it is all the way out. The original late "B" switch would have only been a SPST, just to turn on the lights, all three of them. Some of the later add-on rear lights had a toggle switch on the rease lamp case that turned it from white to red. This switch will ground the generator field at position 2 and 3. Once he gets the pin out information, I'm thinking it can be rigged to fire the front lights at #2, and add the rear light at #3.   [Reply]  [No Email]

First position is off, middle is full field ground the generator, aned the outer most position is lights and full field ground. The fuse is there for generator protection. On your "B", you just need an on and off switch, unless you want to operate the rear lamp separately, but all three lights came on with one switch. You can make the three way do this, but you'll have to trace out the terminals. First position would fire the front lights and the outer position would add in the rear. [/url]   [Reply]  [No Email]

By looking at the picture, can you tell which would be my the hot wire in, and which are my outs?   [Reply]  [No Email]

Here's a photo of the black wire from the "L" terminal on our 52A. Looking at your photo above, the terminal at the end of the fuse on the light switch is the input and the terminals on each side are the outputs. Hope this helps.   [Reply]  [No Email]

I'd just be guesssing.   [Reply]  [No Email]
