Rock,
welcome.
Rom and I are both in Abaco. He just saved me with an Siddley generator ends.
I have a story below and that unit was a Hawker Siddley Genset with a Marathon rear end. ST1 or SR1 engine?
but a few things to check
2. When it stopped working did you have the burnt wire smell?
3. Does the unit have a AVR or just some big ole resisters in the control box area or under one of the covers on the generator, probably at the back end?
4. Does the unit have brushes?
5. Have you found a set of diodes somewhere?
6. What brand rear end?
Some of these questions will help in try to figure out where to look for fixes.
I just finished puting back together a st? 1 with a Marthon 4.75KW end for a friend of mine. Generator and engine shipped up to Abaco from Nassau in two pieces.
Reassembled. Egine started right up--- no power.
After checking this that and the other I found that the stator exciter windings had a break some where. No signs of damage or burning. Probably our fresh salt air.
I had no luck with Lima Marathon in locating a replacement. I talked with someone in Jacksonvile Fla (Their agent that is supposed to cover the Bahamas) who said that he had received a request from Marathon to contact me, but was trying to find out what the part number was and was not having much luck.
My unit was made in 1985 or there abouts and Marathon had no listed part number. Send my Stator Exciter to Jaxsonville Fla had he thought he could match it up with something. He had two stator exciter and felt that one would work.
Oh! by the way, I asked what are the prices of the stator exciter he was thinking of?
one $1500 and the other $1800 $%$#$ I thought. My buddy paid $2,000 for what he was told was a working unit!!!!
Generator repair guys here in Abaco said dump the gen end and buy a new one, not worth fixing.
The long and the short is that I sent the stator exciter to Bond electric in Nassau, they rewond it for $250.00 plus $10 shipping $5.00 a box each way.
Sometime solutions are just around the corner, so to speak.
The rewind should have been easy. Getting the S/E out is a long story F$&!@&G story.
Installed it and the gen works great.
Your problems may be simple or not too expensive to fix, but labour can be high if you have to hire someone.
Good luck. l\Look forward to hearing from you.
