Title: '79 ballast resistor
Post by: enzo on April 15, 2017, 06:30:50 PM
I had some burned wires at the voltage regulator. I repaired them being careful to splice the new wire into the connector one wire at a time.
The engine runs with key in start.  When key is released, it dies.  I don't know where the ballast resistor is and want to check if is good.
Can somebody help me with the ballasted thing!

Enzo.

The ballast resistor is behind the speedometer, it's a special wire with plug ends on each end , but I would check the plug at the ign module before you start removing things ,  you have a two wire plug with a red and white wire , one is hot when you turn on the ign switch , the other is a bypass from the start solenoid that bypasses the resistor to keep the voltage up when cranking , look for corrosion in the plug , (green ) if no volts with key on , bad switch or as you say bad resistor , (rare)  also could be a bad box , if it is org they had problems back in 75 to late 76 , look for a blue tab one the box where the wire come out , that was the fix back hem , later Blaine

Blaine,  Thanks for the info. I failed to mention that this is a 2.3, not that should make much difference. Will look into that.
Took a break from the car. 
Worked all day (9:30-5:00, no meals) swapping alternators, ECU's, regulators, triple checking connectors, triple checking wiring, checking for slipped timing, and, fuel supply. I even changed the ignition switch. Nothing!!!  I'm lost. I don't know what I did wrong, but, it won't run.  I will start up tomorrow early as this my daily driver.  Thinking about getting a later model of something for daily.

Oh!! Man!!  I even got sunburned today, on my face and of course the top of my head, from being outside so long here in the Pacific NW.

Have good weekend everybody.

Thanks Blaine for the help.  Not sure I would have found all the problems.
New regulator and alternator and everything works.
