Have been driving my weber carb'd GL-10 for a few months now and it has been running pretty good, although the weather has been pretty terrible and I have had to drive through some rain. Anyway, recently about a month ago all the power windows stopped working, which I thought was weird. Then about a week ago I go out and its dead. Totally dead. I charge it up and drive again and its good, come out and again its dead. And this time I can't get it to turn back over again. Appears its getting fuel. Fuel filters seem fine, and just swapped alternators. 


Is this a ground problem somewhere? Where would I even start? 


As always the community input is much appreciated.

Additional information, I can't seem to get it to turn over now, no matter how much I am pumping the pedal. It just doesn't want to get going.

    If it ain't broke, you're not trying.

A few things come to mind. First check the power window switch. If this started after the windows quit working, there may be a link. It may have an internal short that's causing your draw. If you're not sure how to test it, just unplug it, charge the battery and see if it's dead the next day. Check voltage at the alternator when running. You should have 13-16 volts. Have the battery tested. You mentioned it's been raining. If you have a water leak and the water is pooling under the carpet, this may be an issue. I'm not sure, but I think there is a module or two mounted on the floor under the drivers seat. Water gets in the connector and causes corrosion which in turn creates a high resistance short draining the battery. If you have a good multi-meter, do a parasitic draw test to confirm you actually have a draw when the car is off.

Ok, you're second post came through while I was typing. lol You need to know if it's getting fuel and spark. First, have someone pump the pedal while you look down the carb. You should see gas squirting out with each pump. Try spraying some starting fluid in the carb and see if it starts. If it doesn't, pull a plug and check for spark. If either is missing, look into why. If both are missing, I'd start looking at your ignition switch.

I'm confused....."slow battery drain"....."dead battery"....."won't turn over"

Dead battery
Bad battery
Dirty/corroded/loose cable ends

If that's not it - I'd be more clear as the title says "battery drain" and "won't turn over" is somewhat ambiguous - I read it literally - the engine isn't moving/turning over. Others might think you mean it's cranking but not firing....

And never forget if you have a carb, they're not unknown for having issues.

To find a battery drain. Unhook the negative cable. Connect a test lamp between the battery terminal and the cable end. Pull fuses until lamp goes out. Also the thick white wire on the bolt on the back of the alternator.
