[T3] FW: Progress Thanks to P.A.

[Dave Hall]

The idiot lights have to have a 12V supply when the ignition is on.  Maybe
that's the problem.  They are not grounded in the cluster at all, but by the
various circuits.

The oil pressure switch simply grounds that bulb when the pressure is low,
the ignition warning light (low voltage/not charging) simply gets grounded
when there's no charge to oppose the 12V that should be on it when the
ignition is on.  The same power lead is used to light the flasher indicators
when the switch is on left or right (either one lights BOTH bulbs) when the
flasher relay is off to the flasher bulbs themselves.  The flasher idiot
lights ground through the flasher lamps themselves.  That's why the main
bulbs flash opposite to the idiot ones.

I won't say that all three faults will be cured, but it sounds as if you've
not got the 12V supply to the idiot light/fuel gauge cluster from the
ignition fuse (ie only hot when ignition is on).  It is carried by the BLACK
wire into the back of the cluster.  I've sent you a photo by separate email.

Replaced the flasher relay with a generic three spade (thank you P.A. for
the suggestion) and now have turn signals.  However, the indicator and idiot
lights flash with the key in the run position and does not change with turn
signal lever position or emergency flasher position.  Also, still no idiot
lights so guess have to make a trip to get an oil pressure gauge with funds
I do not have... :/  

I eliminated  the hard start relay with no change in results, so reinstalled
per directions.

If the white power to relay and the dash wire are held together, the same
lights go on steady.  

Removed wire by wire, with no change in results, except power to fuse box,
power to emergency flasher, the green wire on the emergency flasher switch
and the blue wire next to it.  Tried different turn signal switch and
emergency flasher switch with no chance in behavior.  Any thoughts?  

At least once I get the pressure gauge I can drive it, but not sure how long
I can stand the flasher relay clicking the whole time...


Thanks,
Adriel
