Bought a battery charger last night, pulled the battery and measured 10.09vDC. Dead as a doornail.
Hooked it up and left it all night, measured 13.35vDC this morning. Much better.
Popped it back into the car, reconnected the wiring, measured the voltage once more, still good, about 12.50vDC.
Put the key in the ignition, turned to “on” position to get the fuel pumps running, gave three pumps on the accelerator to prime the carburetors and twisted the key to “start”.
No Mopar whine, no clicking, whirring or anything. The engine simply roared instantly to life.
We’re back in business.
Hello,
Just discovered your blog on your Quattroporte. I’ve always loved these cars and finally talked my wife into letting me buy one, a 1986 Quattroporte. You’ve assembled a great achive on the day to day, month to month challenges of this machine. Unfortunately I’ve one that occasionally starts fine, other days clunk in spite of a fully charged battery. Thanks for doing, and sharing, all the research to clarify this and other issues. Please keep writing!
