In the key-turned ignition-on mode my denso 740 alternators (both) get warm at the pulley after sitting for about 10-15 minutes in the second key turned position when you can see the dash lights on with the seatbelt sign clicking. One alternator is old and worked well in the past, the other is remanufactured.
I never noticed any of this because I had the alternators down below and now I have them mounted on the top left on my 240.
Again, the heat felt in the pulley is independent of the alternator running and is in the mode just before starting the car.
The alternator has a good positive and ground connections with the right gauge wire. The diodes in the alternator are new. There are no odd signals on the warning lights for the alternator in any key position in the dash.
Anybody with a 740 or 100amp denso alternator can verify that the alternator pulley heats up by just sitting in the 2nd key position?
