Squealing starter motor

Well it depends a bit how the remote start is implemented. A remote starter has to enable the ignition (15) and starter (50) circuits to start the car and maintain the 15circuits to keep it running. It may well also have to activate & maintaing the Accessory (X) circuits too. On a 928 it should do this because these control cooling fans, brakes, Lighting, HVAC etc.
The difference may therefore be that when starting with the key in starter mode the X Bus is disabled & 15 bus is enabled while via the remote starter the accessory bus is (likely) also enabled.
On the face of it you'd expect any belt squeal to be worse with higher alternator (& potentially compressor w/ AC on) loading. But sometimes you need just the exactly correct loading to cause the worst noises.
I'd still check/tighten the alt & compressor belts and maybe check the compressor clutch operation...

It sure didn't seem loose, but I cranked the adjuster another turn or two and the squeal is gone. It is a high output alternator with a very small (1-7/8") pulley, recently installed with new belt. I guess the alt load is greatest during cranking and that led to slippage. The remote starter difference turned out to be non-repeatable, maybe it was temp dependent.
Anyway although my alt belt seemed very tight, it was not tight enough, or the new belt stretched a little. A pro probably would have spotted it as soon as he put his thumb on the belt, but I do the best I can. Glad you guys are here to back me up.
Thanks

This is a perfect example of not doing more investigation prior to asking for help, what was given was also a suggested source of the problem.
This is unfortunate as the OP was sent on a wild goose chase, and wound up spending money that didnt need to get spent, on a problem that wasnt there.
Seemingly a simple belt check would have cured all of this prior to the post being launched, sorry for the wrong guess..........

I really thought the alt belt was tight. I also only heard the squeal when the starter was running.
I am grateful for all the help and fully realize that you guys can only base your advice on the information provided.
Thanks, as always

I feel bad about the advice i gave as it was a costly adventure for the person asking for help.
So like i said the more info the you can give the more details that you can provide the better the best guess will be.
Once again, sorry Dave........ Stan

FYI to all.
There is an old school electric motor repair shop in Allentown, PA that can rebuild ANYTHING.
The Curio Electric shop's phone # is 610. 432. 9923
And they are quite reasonable with cost. I have had them diagnose, repair or rebuild many 'projects' over the years. I think they've been in business for about 80 years.
Cheers,
Allen

I have a guy in guelph that is the same thing. He has this dingy old place with paths around all the starter alternators and blower motors. Take all my stuff there now
