Car volt requirements and cheaper jumper cables have both moved away from each other in the last years, it is common for anything other than the best premium jumper cables to not jump some vehicles off. When I sold parts the cheapest jumper cables we sold commonly would not jump off maybe half the vehicles they were used on. I'm not referring to big diesels or monster motor trucks either.

I hope that other guy I lectured the other day about not disconnecting battery from alt while running sees this thread. Way too many people still think that's good testing, can't imagine who ever started that idea. Nowadays it's one of the first things said not to do in new alt paperwork but of course one has to read to see it. Too much work for some.

amen to that. this must be exposed to all of those who believe this method works. i got screwed. money i had for vacation this summer is now gone. i found a ECU that matches mine. now all i need to do is take it to the ford dealer so that they can flash it to work with my key. will i need to just bring my key and the new ecu? or the whole car?

I'm wanting to think car there. They'll at least want the extra bucks to install PCM and get it running to prove out the reflash work. It saves you later complaining the car still won't start, ergo, they must have done something wrong.

Been keeping an eye out for a second set of jumpers, haven't seen ANYTHING on the counter to compare - might have to order some - and the old ones WEREN'T the best avail. when new, just a decent set.

Had the same thought on that guy who was insistent pulling the batt. cable was a good test. Tried to be polite in saying SOME might have built in protection, but I wouldn't trust it (like some Race/Marine battery switches that can be wired with an alternator protector).

AFAIK - This "Test" dates back to cars with generators for charging, and it wasn't a great test then. Amazing how some bad info. can be passed down for years. Must be VERY attractive because of it's apparent simplicity.

Alt. supplies power - battery supplies power - lets see if the alt. supplies enough to run the car without the battery. "FAIL" in the current idiom.

Cheers!

You can't find a place that selles jumper cables? Hell every convient store, corner market, gas station here sells them. I have like 4 or 5 sets.

I think he means a GOOD set, or one that covers everything and robustly built enough to take all the abuse battery cables go through and then some.

I learned the 'do not disconnect battery' lesson by toasting some of the electrics on a '66 Yamaha 100, which had a generator on it. Never again, the factory manual I had back then even told me not to do it. Stupid kid, now I'm a stupid old man, but I don't do that anymore. Could'a been other issue there too, I seem to remember it didn't do it until I revved the engine up really high too. Then smoke everywhere. Kinda like the time I tried to wire in an amp gauge into main charging output lead on a car using only like 22 gauge wire. Sparks and fire and smoke everywhere. Interesting.

I have one set that's 15 feet long and is 2 or 4 gauge wire. Love those but rarely carry them too bulky to just throw in the trunk. Then I have several cheaper sets but have never had a issue using them.

got the car running today, but the guys at Ford told me the alternator is overcharging the battery. they said they were reading 16 volts. as i drove the car home i notice my battery light turning on and off. i also notice that the cooling fans weren't working and the temperature gauge went to the hot zone. now i need to figure out whats causing my fans not to turn on, and i might need to replace the alternator. what could it be?
