Regrettably I did not take any pictures. I searched the web for an electrical diagram as well as any pictures of the VR, but I didn't turn up anything useful. The closest thing I found was a picture from an old eBay auction which clearly shows the circuitry of the VR, but not enough resolution...

mac - Yoda? Ha! Too funny. Thanks!

I got the 2 IRFP450 transistors in yesterday and today I soldered them onto the volt reg. board. Only one of the transistors tested bad, but while I was at it I figured I would replace both. I've not done much soldering, but these components have pretty large pins and the board is not packed...

mac - Thank you for your thoughts. I had not considered hooking up a power source to F1 and F2. I agree any action like that should be handled with extreme caution. If I were to end up doing it I would certainly use a variable power supply and also make use of the existing 3amp fuse and fuse...

Ok, looks like my posts might be working today. If the 3 posts I made yesterday decide to show up, my apologies ahead of time for repeating myself. I started going through each component on the volt reg. circuit board. This is a little over my head so I had to look up a few 'how to test'...

I've tried replying to this thread 3 times already. Each time the site tells me a moderator must approve my post, so this is just a test to see if it is working today. Ah, so I just figured out that putting an 'at' sign in my post keeps it from being posted right away.

@Suprman - I've started testing individual components on the VR circuit board. I'm probably little better than novice when it comes to this, so I've had to search the web for ways to test particular components. At this point I'm fairly certain none of the resistors are shorted and all of the...

I took off the regulator yesterday and examined it. I then took a few screws out and got the circuit board free from the regulator box. As far as I could tell there was nothing glaringly obvious that it had been fried. There's so much lacquer on the board though it's hard to tell if a...

Guyfang - Thanks for the additional part numbers. I figured it had to be the voltage regulator, but I guess I needed to hear it from an expert. So far no lead on one, but I'll keep eyes out. If anyone else out there knows where to find a 15Kw voltage regulator - TRC 19870 (NSN...

Hello. I am new to the forum, but have spent many hours reading the posts here over the last couple weeks. I must first say this forum is a wealth of knowledge and I have learned tons of useful information as well as located all the TMs for a generator I am working on. Thanks to everyone out...
