Hi crew.
Need some help with this one. Pulled up to a set of lights and heard a squeal, faint but there. Took off and it disappears, until stopped again. Noticed this a couple more times before parking at work.
Started it to drive home and it's quiet until halfway and it started squealing again. Pulled up at home, popped the bonnet and it was loud to the point it pissed our dog off.
After a bit of research, likely fault pointed to bad rectifier diodes. Swapped out the alternator for a spare I had and swapped the regs.
Started and no squeal, after a strap is back again. need to swap the reg over as a final check. It's not bearing noise, as I've dealt with that sound, plus the squeal drops off/fades out when killing the power.
So it's only present when the engine is hot. the main power cable is ok, not great and under load I'm losing .4v
Hard to pinpoint but it almost sounds like it's coming from the purge solenoid.
I've got a video I just need to shrink before I can upload.
TL : DR help me with an squeal in the engine bay.
