    I have a 1989 379 Peterbilt with starter problems. Last week I started the truck and the starter stayed engaged, by the time I disconnected the batteries, it burned up. So I replaced the starter with a rebuilt starter, I replaced all my cables - negatives and postives - and the truck was fine for a couple days. Yesterday, I went to hit the button and I got nothing. While looking at the solenoid relay, I noticed one wire was bad so I fixed it and the truck started fine. I turned on and off the truck three or four times and on the fourth time the solenoid on the rebuilt starter stayed engaged. I disconnected the negative post and let it cool down. I connected it again, hit the button and it started fine.

    What is making the solenoid stay engaged? Could it be the four post solenoid relay? Can someone please try and help. Thanks!

    Never ever buy a rebuilt one, The new gear/reduc.type starter cost less than re/built ones.

    P/S if you can buy a new sol. and twist it on you could save it, the china rebuilds dont work for long even if you get a (good rebu one)

    I always bought rebuilt starters. My cost from local shop that does all the work in house was $175. Two weeks ago had a new gear reduction starter installed. Starter cost from same shop that does rebuilding was $309.
    TO answer your solenoid question. I had that happen to a starter of mine in the winter. I replaced and never had the problem again. Maybe the replacement you installed had a faulty solenoid on it. Take it back for warranty and put exchange on. I don't think the cables to your starter can make it stay engaged. Either they supply the electricity to your starter or they don't. Could be your starter switch in the dash is not turning off. Keeping the cranking signal to your starter solenoid.
