Yes the blowers are the same on both models.

Did T1 and T2 test good?

Sounds like the VR to me.

Your test are spot on. But you should continue to see voltage even after its started. One of the features of the unit is to be able to excite the field after its up and running. It does that with the start switch in the start position pin 27. So if the unit ever starts and you see no voltage...

Looking at the schematics your right Guy, L1 does not effect the exciter but I had one unit that took me 6 months to diagnose and the last part left in the output box was L1. I didn't believe that would have anything to do with the problem so I never tested it until I ran out of options. It...

It could be the VR not saying it is not. I think we are trying to help you from spending unneeded money on a VR, when it may not be the problem. We have all been there and spent good money a VR, only to find out it wasn't the problem. But if it is the VR I would highly recommend upgrading to...

That's what the TM says but its not true. Your test does take the VR out and you hooked directly into the exciter board. The VR takes readings from CVT1 and the linear reactor to determine how to regulate the voltage. So if those are not working, the voltage regulator will not work. I've only...

They have a linear reactor on ebay for $69 I think.

On A4 did you test the 56 ohm resistor? I think you may have found the problem in the linear reactor.

Usually when they go bad and cause your issue, you won't have a reading because the coil has shorted so I suspect its okay.

Yes I believe the test you're describing is direct current to the exciter board, which should result in voltage generation. In -34 there is a test setup for the output box which test CVT1, Linear Reactor, A4 (exciter board), etc. It gives resistance values for everything. Most of the time I find...

4 items I would check. CVT1 transformer. Big black transformer on the bottom of the output box. Its actually 2 transformers mounted together CVT1 is in the back Exciter board A4 VR. Sometimes to check the VR you can take number 17 off the VR board and tape it up. Start the unit and if voltage is...
