Why don't you install either an older Delco 25/26SI, or Leece-Neville/Prestolite 2500JB series instead? There are newer and more modern variants available also but these only require a single wire be run to them and are internally regulated. The truck being a 1982 probably had those models as options if not originally installed. Those are the ones I use as any more than one wire really cleans my clock; 😉 1 Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

Frankeintruck Posted May 5, 2019 Author Share Posted May 5, 2019 Would like to keep it all original.been trying to find a free manual online, am unsuccessful. I think I find one, then it leads Me to a dead end. Also been working on my two speed. Once I flip up, doesn't always flip back down. I have to flip it back up and then it will go down....blew out all the lines. Has new regulator. ?? Quote Link to comment Share on other sites More sharing options...
smorse54 Posted May 5, 2019 Share Posted May 5, 2019 Being an 82 there should be only 2 wires, the positive goes to the hot side of the starter solenoid and negative grounds to the block.I haven't seen any 350's with 24 volt start and series parallel switches.If so its a different game entirely. On the 2 speed is this a Fuller Roadranger transmission?If so it sounds like the slave valve is sicking. You can remove it and free it up.It's located on the left side and all the hoses go into it.
