johnny_h Posted March 7, 2008 Report Posted March 7, 2008 Would a knackered starter solenoid stop a coil from sparking?
Muttley MK2 Posted March 7, 2008 Report Posted March 7, 2008 Well if the starter aint turning then the coil wont be sparking!
Tom Posted March 7, 2008 Report Posted March 7, 2008 on cranking your coil is fed from the starter so its possible - saying that i'm not sure cleaning your loom in the washing machine would do it much good
johnny_h Posted March 7, 2008 Author Report Posted March 7, 2008 on cranking your coil is fed from the starter so its possible - saying that i'm not sure cleaning your loom in the washing machine would do it much good The loom is fine, the starter didn't go in the washing machine, just the wires The starter solenoid won't turn on the key and the coil tested ok but when bridging the two posts on the solenoid the engine turns but no spark from the coil.
Savvi Posted March 7, 2008 Report Posted March 7, 2008 I think we need to know what car it is and the year so we know system is fitted ? It sounds like you have lost a feed that runs the coil and the crank / ignition side of the starter ? Do you have voltage at the + side of the coil ? Does it have points or electronic ignition ? Alarm / Immobilliser fitted ? Could also be a faulty / burnt out ignition switch.
johnny_h Posted March 7, 2008 Author Report Posted March 7, 2008 It's a '71 mex with x-flow and lumenition ignition module which was replaced recently. The coil works fine when tested using a wire to earth.
Savvi Posted March 7, 2008 Report Posted March 7, 2008 The coil works fine when tested using a wire to earth. ? What does this mean ?
john_3.0s Posted March 8, 2008 Report Posted March 8, 2008 well with a live feed at one end of the coil grounding and releasing the neg side will cause a spark at one of the plugs (assuming the dizzy rotor is OK). can you measure any power (+ve side) at the coil when measured to a good earth on the engine somewhere and the ign is on?? have you got a feed and ground onto the luminition module OK?
Savvi Posted March 8, 2008 Report Posted March 8, 2008 Would a knackered starter solenoid stop a coil from sparking? So are you now saying your getting a spark from the king lead (Main lead from coil to cap )? Is the engine now cranking ? If so it sounds like you have a rotor arm or distributor cap problem ? However if the starter is working but turning slow it may be it's drawing all the power out the battery and not allowing enough current for the ignition system.This will give you a weak or no spark.
johnny_h Posted March 8, 2008 Author Report Posted March 8, 2008 Never mind. I can't be arsed to explain when I don't know what I'm talking about myself. thanks anyway.
