Question about Vehicle Parts & Accessories

Loss of acceleration

Sorry for not speaking in the video. Received a battery/alternator error yesterday, the engine died, restarted and now won't respond to accelerator. If it was clear enough in the video, while idling the engine is revving up on its own constantly. I checked the voltage on the battery and alternator, and that seems to be ok.

Hi! supafuzzy
After recharging the battery, load test, a bad battery dirty terminal could be a problem. With the engine running what is the Voltage at the alternator and battery. It should have 13.4 to 13.8 Volts, at both locations. R&R Alternator. This should be the voltages at the fuse pannel. The HEI ignition needs good voltage for a hot spark. Other things to check if alternator and fuse panel have good voltage, Ignition Switch, Fuse Panel, Connections at Distributor.

SOURCE: Hi, I am working on

Most alternators put out around 14.7 volts. Yours is alittle high. You might check it with another meter to be sure. Voltage does drop when the engine is running and has a load on it. ie lights, A/C, Blower. radio. As long as it stays above 12 volts it is working. I have bought parts before that last only days, so I wouldn't worry about the first alternator. If the voltage drop continues (say to 8 volts?), Then I would check wires (loose connections). The first would be the ignition wire going to the starter. On your year the battery power went to the starter and most of the ignition power ran from there. There could be several wires from the starter hot side. ( sorry I can't be exact, I haven't worked on one for awhile). Also check the grounds, battery to engine, engine to body, battery to body.

Keep charging battery an it dies


Sorry to say that it sounds like one of the cells in your battery has 'died'. It will show a full charge when sat on the bench but as soon as you put a heavy load (like the starter motor) on it it won't want to know. Only solution is a new battery.

Hi there !

I won't say its an alternator problem because the alternator only charges the battery when its on, And it should start with the jump cables even if the battery and the alternator are bad. your Issue is not clear. Does the car start when you jump it ?

It's either your battery or alternator have them tested. If your alternator is bad it wont charge the battery. If the battery is bad it won't hold the charge from the alternator. Good luck!

first, check (or have checked) the battery-it may have a damaged cell and is no longer putting out 12.5+ volts, which is necessary for a modern engine's ecu-a digital voltage meter (less than $15) will tell you is this is your problem.

There is a diode in the alternator that you fried the instant you disconnected the battery....go get a new alternator. This was an acceptable test on much older cars, but not these days......

Battery or alternator


I suggest you pull the battery and alternator then take them to a auto parts store for testing. Most major chain stores will do this for free. Another alternative is to get the car running with a jump or battery swap. After you get the car running remove the positve (red) battery cable. If the engine dies the alternator is not working. If the alternator is bad you will want to get your battery checked. The alternator going out could have damaged the battery so that it will not hold a full charge. Good Luck!
