Cat 922B alternator problems

Both the 922b and 944 loaders we have are direct electric start and used generators instead of alternators. The 922 is a sort of chameleon though, so no telling what it came from the factory with. It actually has a DELCO 10SI 1 wire alternator installed on it with a home made bracket I welded up. Very simple and common as dirt if you need another one.

Do you have a local generator and starter shop? If so, I would take the unit AND the regulator to them and have them check it all out. Once it works, then you can reinstall it and if it does not work you can be sure that the problems lie somewhere else.

Generators typically use electro-mechanical vibrating reed type regulators that are prone to go out of adjustment etc. Sometimes the simplest solution is to replace with new which is what most shops will do. I can sometimes tweak them a little and get them going but then I have done it enough that I know a little about them.

well my 922B is 24v alternator model 42704P 65 amp. it's a 1 wire alternator but as we speak the voltage reg dose not work. when i got the loader the P.O. was running 12 V and trued over very slow after switching to 24 V made all the difference in the world. the glow plugs and voltage reg are on the list of things to fix.

Many 922's and 944's have been converted to alternators over the years, but all were fitted with generators off the production line I believe.
I have a very late series ('69 build) 74J, and it still has the original generator. I really should make the effort and convert it, as it only gets fairly short running times and the genny only throws about a 5amp charge.

Find an automotive electrical shop. Take alternator to them along with any external regulator. You will be looking for a place with junk piled in the corners and at least one guy with grey hair.
