I had been feeling pretty good about my Onan as I had it running really well thanks to many here on the net. Well today, no AC output. Worked fine a week ago but today no AC. I am not aware of anything I did different or unusual.

I went to Gene Fisher's site and read up on the issue. Everything seemed to point to the Bridge Rectifier (BR). I removed my BR, carefully noting the orientation and labeling each of the wires.

I had a spare BR so I thought I would swap it out. It is an aftermarket NTE5328 that has a different orientation of the pins so I had to modify the plastic base by drilling 1/4 inch holes so the wires can align properly with the pins.

Here is my problem. I was very careful to note the orientation of the original BR and carefully label all the wires. This is important because the BR can be inserted four different ways, but only one way works. I am certain that I can get the old BR back in properly but I don't know how to properly orient the new BR.

The only markings on both BR's is some numbering on one side. The new one is numbered NTE5328. I oriented the new BR with the numbering in the same position or orientation of the original, but I don't know if that is necessarily correct.

I did install it that way and started the Onan but still no AC being produced. I don't know if it was a good BR or if I have oriented it incorrectly? Any help or ideas would be greatly appreciated.

I did measure the voltage across control board pins 8 and 11 and I am only getting 2.3 volts. I think my next step will be to disconnect the voltage regulator as I understand it is not required and could cause problems if it failed.

How do I know how to properly align or orient my new BR?
Is there anything else I should be trying?
