Re: Starter issues, again.
I am contemplating replacing the starter bolts when I drop the starter again. The tranny I have is a 1975 TH-400. What are the bolt specs I need to look for? Thanks!

That really baffles me too. Something REALLY sticky in the starter? Intermittent cell in the battery? Intermittent solenoid? Those kind of things are a bear. Think if you get a new starter, flywheel, and the heat shield you should be OK. As for grounds, the factory ran a ground from the driver's rear, outboard valve cover bolt to the frame(?) . Seems a lot of people never reconnect them whenever the do anything to the engine. Try that if it comes to it.

I will definitely get a another ground cable to run off the engine to the frame.

Re: Starter issues, again.
This has nothing to do with the grinding issue (flywheel, starter drive), but have you considered a remote solenoid? I hate to bring this up because it was a hotly discussed issue (pro and con) a few weeks ago and it will likely bring out both sides of the issue again. The "heat soak" issue is identified as a condition of cold start OK, hot start like a dead battery - really excess heat causing excessive resistance in the wiring - or, take your pick of other theories offered regarding heat soak.
I have read that GM had a shorter/weaker spring used for big blocks to help with the heat soak engine, and that NAPA solenoids still use this type of spring - don't know if this is true. Here are some discussions, including heat shield and GM starters: http://www.chevytalk.org/fusionbb/sh...hp?tid/166101/ Light GM solenoid spring: http://cgi.ebay.com/ebaymotors/65-66...-/360360427675 Reference to NAPA and GM part numbers: http://www.binderplanet.com/forums/s...ad.php?t=86431 |

Re: Starter issues, again.
I got the morso heat shield installed. I did not replace starter as it was acting proper. Not entirely sure how much life it has left. Did get to see some fireworks while I was fitting the shield to the starter. It grounded out onto the headers. It was a rather PIA install as usual.

Re: Starter issues, again.
It is definitely a heat issue. I have headers and experience this anytime I run hard, and the engine bay is feeling toasty. I will look into wrapping and shielding the starter.

Re: Starter issues, again.
The current at the time I installed the heatshield finally died. This last starter is a bit different, but has been holding strong for about a month now. The heat shield fixed the heat absorbtion.

Re: Starter issues, again.
and before this, I was thinking it was the battery, until I wired up the gauges, and I am looking at 14 V while driving and 12.5 V when left overnight or after driving. That made me think hard at the culprit...and yes, it has to be heat. Funny story, I was changing spark plugs on the truck, and wanted to fire it up for a second to make sure everything was good before I started on the other side. I promise you - I let it run for no more than 10 seconds. When I went to touch the headers then, they were super hot....and mind you, the truck had been sitting all day. LOL. Those headers are very toasty.

Re: Starter issues, again.
If you are getting reman'd starters, keep an eye out as to the terminal style. I have encountered a 2 terminal and a 3 terminal. The 2 terminals died very quickly and seemed to have a much harder time cranking than the 3 terminal version. Not certain what is different on the inside, but the 3 terms work better.

Re: Starter issues, again.
I had the same problem after installing 454 in my 83. Shop said batteries okay, starter was pulling too many amps meaning it was bad. Went through 4 reman starters, they built me a starter with a welded armature, $100.00 just for the armature, I made cables with welding cable, installed heatshield, seem to do it more after warm. Put up with it for well over a year or so. One day it wouldn't start after stopping on a trip, I pulled my jumper cables out and jumped it from the second battery and it fire right up. Next stop, I bought a new main battery and never had that problem again.
