Restoring powerhouse genny - any info available?

[Jembow]

Started taking the field coils out, got a new set to go in, any tips?

The MAFCA's Restorer magazine had a detailed article last year all about restoring powererhouse.

The Model A Generator book by Paul & William Mcree is the best I've found so far. Be very careful how you record where the coils go. They alternate the winding directions for polarity in the case so a person has to get that right for it to function properly. I was involved in a lengthy discussion about that recently so there is a thread about that on here. Most books don't get into rewinding the field coils.

Thanks. I'm not in MAFCA but may find a friend with that magazine. I have rewound coils from a parts vendor which I trust are correct and will note the location of the old ones before they come out.

Search this forum, I’ll bet that there is some good info here.

Tom Wesenberg was our resident specialist on these units and their characteristics but he passed recently and is still sorely missed. There are a lot of posts by him for the powerhouse units. He preferred them over the Autolite types.

This is a recent link. Steamgas made a diagram of his field coil arrangement and put it in an adobe file for folks to use in the future.

Years ago i ran a Powerhouse on my '28. When it quit I went to the later unit. When I talked to the "old timers" they all said the major problem was with solder joints going cold inside the Powerhouse.
