On two occasions recently on pulling onto my driveway after a long journey my car won't restart after turning off to unlock the garage door. Luckily I can then just push the car in but with a European tour booked in the summer I'd like to sort the problem.
When I get back in after opening the garage the lights on the dash dim when I turn the key to start but there is no click. 20 minutes later it will start right up. Is this the problem that will be solved by a hot start relay kit or just a good old fashioned sticky solenoid? I'd rather do just the relay or just replace the solenoid so which is it? Thanks guys |

I believe it and understand it. That's the same reason a condenser (aka capacitor) was put in place in parallel with the points. It gives the voltage spike a path to ground that is less resistance than the air gap between the points. Kinda like a catch can for the spark.
I don't have training in analog electronics, just digital. But I have read the basics. So why not put a capacitor at the back of the ignition switch? It would be cheaper, it would dampen the electrical spike, and it would not add another circuit to the car like a relay does. |
