Energy drawl / tach problem
Hi all... hoping someone can diagnose this problem ..thought I had my car runnin good, about to go to the smog shop and now, this problem came back, it happened before I got a new starter and quit for a while. I have a good alternator and battery, but something is draining my battery, Not overnight or just sitting there, but Only after I let it idle for a while. As soon as I shut it off, it will not start back up unless I charge the battery or jumpstart it. It will idle fine though, will not stall or anything, I'm thinking maybe something is drawling all the juice out of it while it runs?? Also, my tach has been all out of whack latley. when I shut the car off the tach will stay at the rpm's that I shut it off at.. As soon as I get to the point to turn it over again, it resets to zero until it starts. It also will not let the rpm's reach past 3k, even if the engine is reving higher than that.. Any suggestions on what to check, maybe a bad volt. reg.? and could the tach prob. be the tach itself or something affecting it??

take it to a battery place and have them load test it. get the charging system tested same time. most places do it free. that would be step one. nothing can drain your battery while running and the alternator is working correctly.
Nothing? Cars and people can always find a way to do the impossible....NEVER say never till the problem shows itself. Which is why we appreciate people posting the ultimate resolution so we can all learn!

Battery and/ or altrenator is bad.
Your all just guessing! A voltmeter can be had for $3 from Harbor Freight. Your going to need it if you own this car. The checks I described is a load/batt/alt test all in one!!! In your own freaking driveway!!

I will do that volt test tomorrow on it and post results... I was just curious though, does any of the fuseable links have anything to do with the charging system? One was melted in half and I just replaced it earlier, but I know a couple of those go to important parts such as the fuel pump/relay and the ignition.
You might want to find out what caused the fusible link to melt before you just replace it and allow whatever is overloading the system to cause more damage than a melted fusible link.
It would appear that your car is a typical candidate for the proccess of cleaning every electrical connection and inspecting every wire from the front bumper to the back bumper.

if you don't get the battery load tested you don't know anything regardless what speednick thinks.
The battery is fine, I switched it out with the battery from my other car and it works great just like the one I took out of it.
"Sounds like you have a drawl." It may pop a fusi-link when trying to charge a dead or low battery. Also a short will pop the fusi-link, (a fuse like wire.) Norm K.
