I understand. finding out I could modify the 400hz regulator to a 60 hz unit with some components swapped. was kinda hoping the same for the governor. I have 2 new 400 hz control boxes. so was hoping if needed to. I may be able to rob some of the goodies out of it where it applies.

Ok I'll dig it out and check those references! I appreciate your help!!

does anyone know if the 60hz and 400 hz Woodward speed controls the same or similar?

board part numbers. 60 hz 1st then 400 hz. the diode part numbers are the same. so the 400 hz boxes they cant give away. the 60 hz boxes are 699.00 and up. a good way to save some money if you are half decent at soldiering.

and the cover markings of the 60 hz and 400 hz.

pictures of the transformers. 1st picture is 60 hz. 2and is 400 h

sorry pi led the wrong pictures. let's try this again.

ok found something very interesting today! the 400 hz regulator and the 60hz regulator use the same internal boards , and transformers. the big difference is resistor values and some capacitors and resistors added , and some not there. it appears to me you could take the 400 hz board and swap...

Well I have finally ordered a replacement voltage regulator for this Gen. I'll post a update once I receive it and have it installed. question is this considered a weak link or high failure item on these generators? how about the blue box governors ?

Unfortunately I believe I have a bad controller box. I still have the same problem. By the way it's a 806A . I'm saving up for a new control box

Ok I have a update. 1 of the things I read in the manual talked about the magnetic pickup switch to show the control proper RPM for a flash. So I pulled the 1 connector out to measure resistance. went to remove the second 1 it wouldn't budge. after some brute force it came apart and it was...

Well after not starting this Gen for more than 2 months I'm having a similar issue again? The difference this time is the RPM is up at 1800 + with the knob I can turn it up to 2000 RPM . I can manually flash the gen, But as soon as I let go of the start switch the power and freq drop ??? any...

OK Boys and Girls !! I got this figured out ! Ok a old friend came over with a tach to see what the engine is doing. We put the tape on the balancer. fire it up and it was running 1550 to 1625 RPM . Still have low frequency and voltage. I went to go get a small screw driver and just before I was...

Bought a tach last night. It should be here before weeks end I hope. A friend is swinging by tonight with his fluke so I'm hoping we get somewhere . I'll look in to extech in the meantime.

OK I'll check that tomorrow. I use to have a fluke model 97. But someone I guess liked it more and it grew feet :-(

Also on page 230 it shows the pump adjustment on the low speed idle. Mine had been backed out shout 2 1/2 turns. I adjusted it but it only increased the frequency by about 1 hz When it was back where it was.

Is it a digital input ? Wasn't sure if it is a D/A setup ?

Unfortunately my meter is a cheapy rat shack it . It just does ohms. AC. DC . It's about as basic as they get :-(

Maybe you might know. The blue box (Woodard unit should have a input for rpm. I noticed a pickup sensor on the bell housing)

Also I went over all of the wiring and only found 1 issue even though it really shouldn't be a issue. The GND wire to the output board was rubbed threw it's shield against the gen housing. Being that's grounded as well it shouldn't have caused any issues.
