Sourcing a Starter Solenoid




The Best of Corvette for Corvette Enthusiasts

This is exactly how my solenoid looked.
If you have a starter solenoid has cracked you CAN purchase a solenoid and avoid purchasing a whole new starter. You just have to find a starter/alternator shop or possibly an auto electrical shop that carries it, or can order it.
In my case, I had to get creative because I have a turbo mounted to the exhaust manifold and the starter will not drop-out completely unless I drop the turbo from the ex manifold (which is a PIA with an oil/water cooled lines, housing bolts, heat shield etc).
I disconnected the starter completely, unbolted the exhaust manifold and turbo together from the cylinder head and exhaust (which gave me a few inches for my hand/arm to painfully access the sarter wires from above between the manifold flange and cylinder head). I then rotated the starter around towards the cylinder head to access the solenoid.
Here's the good part; I mixed up quick curing two-part epoxy and coated the broken/cracked plastic around the brass terminal that connects the positive battery cable to the alternator. (It’s the outside terminal that always cracks. See pic above). Keep in mind my solenoid was cracked bad enough the brass terminal/stud fell out when I loosened the wires! I then applied several thin coats of epoxy (which set-up in less than a minute) and let it completely cure for 24hrs.
I then remounted the starter and connected the two wires back on the terminal and DID NOT OVERTIGHTEN the nut to the brass stud!
The solenoid holds up great even with the heat from the engine and turbo (although I have shielding between the starter and the turbo).
I’m at 14.2v consistently and it cost me $6 for the epoxy.

Why pay for a new starter?
The brass terminal just holds the two wires in place/together. Good quick-curing epoxy (see my post above) will reinforce the cheap plastic as good as or better than new. At the most you can replace the solinoid for $15-20. Dropping the starter is about as easy as changing the oil.

I could not find anything physicaly wrong with mine so I removed it and took it to a shop. They pulled it apart and informed me it was ok but had some indications of failing in the near future. I bought a new starter cheaper than he could rebuild mine (kept my old one for a emergency backup even though I probably would wait for new one because of header removal). Sad to say but my charging issues didn't clear up after the replacement.
Also, what spark plugs do you use? I remember seeing spin monster post about a certain plug causing a service charging system code....
And make sure the power wire coming from the alternator isn't melted from the heat...

I cleaned all contacts -cleaned all grounds- put a heat shield on the new starter- replaced the alternator -removed the NKG plugs- rerouted the alternator wire that was near plug 1.
When I first got the car it showed 14.5-14.7 .About a year later it was showing 14.3 and I startered looking then. I replaced the battery with larger Diehard and that did not make any difference.

When I bought the new starter I spoke to the owner of the business and he checked on his computor for causes. Almost everything I had already done was mentioned. So I am going to take it in there soon and let them look for the gremlin.
