Hi. I have a '75 that hasn't been run in over a year. When I try to (jump) start it, it turns over only very slowly - once every second or two, and won't start. I haven't had to deal with this situation before, so I'm a bit at sea. Could anyone suggest how I might proceed to trouble-shoot this?
Thanks in advance.
How is your battery?
It can be. Are you crossing the terminals on the starter to see if it turns faster? If so, then your start circuit is draining too many volts and you need a remote start relay (hot start). If it still turns slow, with a charged battery, then the starter is toast.
Also, I am completely ignoring that the engine has no oil, or other more egregious internal engine issues may be the cause. Start simple and move from there.
Seriously? A dead battery won't start the car with a jump?
A dead battery is just sucking the juice from the jumper. You must let the jumper car run for a while so the dead battery will build enough charge to turn the engine.
Btw, these cars have alternators, not generators. So does the newer car your jumping it with. An alternator will not charge a completly dead battery.
Also, if you leave a lead acid battery on the concrete floor for a year, it will suck the life from it.
Just because you have a good battery as an assist, the dead battery can be a drag.....ressitance is futile.
Put a meter on the battery in the car. It needs a minimum of 12.5v. Use an external charger. Charge it......if it still turns slowly check the volts at the starter. You may have cracked cables and corrosion creating a drop.
BTW, alternators are NOT designed to charge a battery, they maintain a battery. Expecting the alt to bring a battery up to full charge is a lesson on how to repalce the alternator. BTDT have the tee shirt to prove it....
Thanks for the suggestions and for correcting my misunderstanding of what was going on there. I'll put an external charger on it and take it from there.
