Points alway hot???
Hey guys.. the points in my 28 are always Hot, I traced all the wiring according to my Model A manual and everything looks correct. Can someone point me in the right direction please? That is unless they're supposed to be..
Thanks in advance! Jim |

Re: Points alway hot???
What test did you use to determine they are always hot? Will the car not turn off with the key?

To make a long story short I was just giving everything the "once over". cleaning the carb, flushing the block and radiator cleaning and checking the gap on the points... When I touched the screw driver to the points I get sparks.. That's when I went through all the wiring, all looks good. |

Re: Points alway hot???
Just looked more closely at the Wiring Diagram.. The Diagram shows a Positive ground system.. Mine is connected Negative Ground... Could that be my issue?

Is it even possible that the ignition switch somehow got wired downstream from the points?! |

Re: Points alway hot???
Soon as I get home I'm going to wire the battery to positive ground and do another check over over the electrical. I'll post the results

Re: Points alway hot???
I already reversed the coil when I was going over the wiring. The only thing left is the battery and spark the bolts on the cutout..

Re: Points alway hot???
Just to be clear, as Chuck indicated, there is zero chance that your problem is due to battery polarity.

Where are you placing the test probes when you are measuring the voltage? One lead should be on the engine block and the other moved from point to point.

Re: Points alway hot???
Problem Solved! The ignition switch failed and it's actually working backwards! I called Snyders and a replacement is on the way..
The guy on the phone was says those original switchs can be very temperamental. Thanks to everyone for your input! |

Re: Points alway hot???
Your ammeter will be wired backwards also.
I wonder if the "spark at the points" was residual current in the capacitor (condenser)? Are you actually measuring voltage at all times at the points?

Re: Points alway hot???
I was using a basic test light. With my switch pushed IN I have No light on the test light But when I turn the key and the switch pops out my test light lights up..

Re: Points alway hot???
You do know that when you push the switch in it not only opens the circuit between the coil and distributor but it also grounds out the wire going to the distributor.
