Does anyone out there know if a relay should be warm to the touch? I recently resolved a no-start problem with my '89 740 by replacing a fuel pump relay and a noise suppression relay. All is well, however through this experience I have found that different relays are either warm/hot, warm or cold to the touch.
My original power window relay (first metal relay on left) is pretty hot.
New fuel pump relay just warm.
New noise suppression relay on coolant bottle hotter than warm if that makes sense.
All fuses are cool to the touch.
Comentators on this board have said that 1) "A hot relay is a bad relay" and that 2) "Volvo relays typically run warm anyway".
What's normal?....and if it's contacts how do you clean them?
