After successfully changing the mechanical fuel pump on my 71 spider, my red dashboard ingition light is now on all of the time. I no doubt stressed several wires around the coil, but I do not see any broken wires. I charged the battery with my charger but have done this many times in the past. Could I have an alternator or voltage relay problem? Too co incidental since I had to install the new fuel pump a couple of times before I got it right. Thanks for suggestions.

Thanks...I was afraid that was the case....At least my new fuel pump is putting out plenty of fuel! It is about time for a new alternator and regulator anyway.

Re: Red ignition light on
Could a dislodged wire connection from the alternator cause the light to glow? Seeing that you did the pump and said that you disturbed some wiring, maybe that is the cause?

Re: Red ignition light on
Reading the manual apparently there is a relay that when energised keeps the light off. It is located near the fuel pump so before I go after the alternator, i will check out the relay and wiring. Research helps before jumping to conclusions. Thanks.

Re: Red ignition light on
Rroller123 hit the home run. After some examination I found a wire knocked off the voltage regulator and that solved the problem. I cleaned all the nearby ground wire terminals while in the mood. The car is running great and we took a victory lap in the rare Seattle sunshine. This is a great forum and so many helpful readers. Thanks to all.

Re: Red ignition light on
Nah, I have just done the same thing myself multiple times and caused myself many headaches. In fact, just did this with one of my driving light relays when I put in the new master brake cylinder. Wondered why the Hella 550 driving lights wouldn't work when just changing brakes?? Wire pulled off when manipulating the MC out of course....
