The car did start today but only ran for about 20 seconds and then shut off. I unhooked the MAF sensor and the car restarted and idled real nice for several minutes , then I shut it off. So it seems a new MAF sensor is needed.
The battery is ok at 12.6 volts with the car off and when running the gauge registers 13.3 volts. Is it possible that the faulty MAF sensor could mess with the computer that then messes with the gauges to give that 11.4 v reading yesterday? A couple of weeks ago I had driven about 10 miles and suddenly the gauges went into flicker mode, the battery registered 11.8v and the motor began chugging. I pulled off the road and the gauges stopped flickering but the battery voltage kept changing between 11.8 and 12.4 volts. The drivers power seat no longer worked but the passenger seat worked fine. I continued to my destination, shut the car off, cleaned the battery terminals, fiddled with the wiring under the drivers seat and after sitting for 2 hours the car was working fine, no flickering gauges, normal battery gauge at 13.3 v and driver power seat back in operation. Can all this electrical stuff be related to a failing MAF sensor?

Today's Featured Article - 12-Volt Conversions for 4-Cylinder Ford 2000 & 4000 Tractors - by Tommy Duvall. After two summers of having to park my old 1964 model 4000 gas 4 cyl. on a hill just in case the 6 volt system, for whatever reason, would not crank her, I decided to try the 12 volt conversion. After some research of convert or not, I decided to go ahead, the main reason being that this tractor was a working tractor, not a show tractor (yet). I did keep everything I replaced for the day I do want to restore her to showroom condition.
