1976 ignition relay

[darom]

Hi guys,

 

How many ignition relays (passenger side) do our cars have? 1976 FSM shows only one - page BE-36. It appears that the PO installed two of them (part number B5230-W0500) on my 76. The oil/water temp/voltage/fuel gauges don't work (the illumination does work). I thought maybe the voltage regulator was bad (per FSM), but the PO installed a brand new one from Kragen's. The next thing FSM suggests is the ignition relay (singular, not plural case). Attached you will see my ignition relays.

 

I found the Courtesy site showing the original relay number being 25230-89915. I had an old relay laying around with the same number, when I installed it instead of that 2-pack I had, the car almost started at half-turn of the key and the relay started making loud buzzing noise. I turned off the car immediately. Obviously, the PO hacked the wiring.

 

Could someone do me a favor and check the continuity from the water temp sending post (engine non-running) to the frame? Is yours grounded? Because mine is - this doesn't make sense! The same happens with my oil sending unit, it is grounded. WTF.

 

All the fuses have been tested with the voltmeter. I am getting 11.2V on the fuse that handles gauges.

 

I appreciate your help, I posted the similar post in the classicz's forums.

 

Thanks,

Den
