Anybody know what voltage the glow plug timer relay puts out. I'm
talking about PRC6913 on a '96 300tdi,
Although the input is 12v the relay output starts at 9.5 and climbs to
10.5 (measured at the relays spade) before the timer cuts out about 8
seconds later. This heats the plugs but not enough to glow which only
seems to happen if I strap the plugs directly acoss the battery.
I've tried a new relay and get the same result...and also tried
earthing the relay straight to the battery - I assume the temperature
sensor is within the relay body itself. Perhaps the warning light or
timer mechanism is 'stealing' the extra voltage ?
I'm looking for the cause of the big blue cloud that follows me around
for the first 5 minutes on colder mornings
