Date: Sun, 15 Apr 2007 22:48:10 -0500 Hi Kenyon,I'd check for 12 volts at the positive side of the coil with the key on. If there is 12 volts there, the car should start when you jump the starter relay. You can at least verify that it will start by running a jumper temporarily from the battery positive to the coil positive terminal. Make sure the car is in park when you try this obviously. With the key held in the start position, it should read at least close to battery voltage at the starter relay terminal below the main battery cable connection. If not, I would take a good look at the white plastic connector from your ignition switch located on the lower portion of the steering column. I've had quite a few of these melt and cause bad connections.Stevan Miner Miner Auto Service Winnebago, MN----- Original Message ----- From: "Kenyon Wills" <imperialist1960@xxxxxxxxx>To: "IML" <mailing-list@xxxxxxxxxxxxxxxx> Sent: Sunday, April 15, 2007 5:10 PM Subject: IML: electrical question. I hate electrical.72 coupe ran and drove fine. Parked for 2 weeks. Now no start. When key is turned, the SIGNAL SENTRY light lights up, which is normal, as there is no oil pressure to trip the switch that turns it off. Turning the key further to just before starter relay contact illuminates the BRAKE SYSTEM light, which may be part of the diagnostic test of the bulb, or more likely is because the booster is fried and has been. I've put about 10 miles on the car with the BRAKE SYSTEM light illuminated, and there is a new booster and complete brake system awaiting the car in the garage, so that is a known problem - should not be related to the no-start problem. Anyway, when the key is just a hair away from tripping the starter relay, I get both lights that start solid and then start to flicker agressivley before slowing down and winking out. Both lights flicker on and off with increasing frequency, and the entire fuse block seems to be getting rapidly interrupted power, with clicking as the relays are energized and then shorted of power. The wiring diagram shows that the relay making the most noise at the fuse block is the power window relay switch, and disconnecting it stops the flickering current noise that is very audible in it, but I think that is a symptom and not the problem, as the lights continue to flicker on and off. The symptom indicates to me that the ignition circuit is flickering on/off, tending to off after starter relay is connected and it heats up. I got a cough or two out of the engine that coincided with the lamps being illuminated in that second, but the thing is dead otherwise. New engine, battery, etc. under the hood. Ignition switch? Shorting the relay with the key in RUN does not start the engine either, although it does turn over, obviously. I cleaned out the bulkhead connectors during engine swap - do not suspect a corroded connection, and since I've not touched wiring since driving it, do not suspect a loose connection there. Thoughts?
