Car Forum / Driving, Maintenance, Tuning / Maintenance and Repair / February 2005Geo Metro - No electrical power at al
I fear the worst, but hope someone here can give me some cheap alternatives. My wife took the portable jump starter and decided to use it as a batter charger while the battery was still hooked up to the car. Not a good thing and I told her not to do it, since she blew out the last jumper like that. Well, she did it... I came home and the jumper was dead. What are the repercussions to the car? I just installed a new battery and like the old one, it does not crank and I cannot even jump the car. There is no power to anything... wipers, lights, signals, etc. It is a 1989 Geo Metro and we have no manual. Is there a main fuse possible that could have been blown or another cheap part that can be replaced? Initially I was able to jump it with the jumper after I bought it, but haven't been able to since she hooked it up to the AC. Thanks in advance... OK, I did some more research and located the fuse box under the hood. THere is definitely a 60 amp fuse blown. I inadvertantly touched tweezers to the 2 ens and the lights came on. Would that also control the starting current? How do you get it out? There seems to be a small clear lid I pulled off (which fell down into somewhere... I suck at cars), but the whole plastic assembly won't budge. > OK, I did some more research and located the fuse box under the hood. > THere is definitely a 60 amp fuse blown.

I don't know exactly from experience on your Metro, but I am pretty sure you jumped the battery backwards, resulting in a blown main fuse (sometimes called "alternator fuse"). Usually these main fuse link cartridges 60A and greater are held into the underhood fuseblock with two small bolts. To get to the bolts you will need to partially disassemble the fuse box (usually involves releasing tabs around the plastic fuse link block inset and pulling it as far out of the fuse box as the thick power wires will allow). Unscrew bolts, replace fuse, and reassemble. Then use the battery booster correctly. Also, it sounds like you are using the booster with its little AC adapter plugged in to "charge" your car battery. I doubt this will do much appreciable charging as it is designed to charge the booster only, and slowly at that. Toyota MDT in MO THat explains the bolt I saw there then... yes, that is probably it. Now if that fuse blew like it did, would it stop all electrical functions on the vehicle, including cranking and accessories? > THat explains the bolt I saw there then... yes, that is probably it. > Now if that fuse blew like it did, would it stop all electrical > functions on the vehicle, including cranking and accessories? Yes. If you can see the bolt(s) then perhaps you have the easier to remove fuse cartridge with 90 degree bent terminals. I was refering to the straight leg cartridges that are harder to remove. Sounds like a simple fix.

A bad battery ground will also do this. The metro usually has two grounds, one large one attached to the transmission and a smaller one attached to the main car frame. Clean both sides (surfaces included) with sandpaper. Because of the cars age I'd also replace the battery cable outright...should only cost $8 or so. Make sure the wire grounded between the engine (usually under the distributor) and the frame is also intact. I would also recommend cleaning the other grounds, especially for headlamps. The grounds are fairly easy to spot (all around the firewall and inner frame under the hood). Should be about 3 or 4.

Not a what's wrong with that -- as long as positive goes to positive and negative to negative!!! no problem - perhaps you tried negative to positive and positive to negative -- Batteries terminals would weld and the good battery would pop or explode >>> your electrical system would be unaffected!! > good thing and I told her not to do it, since she blew out the last > jumper like that.

Is there a main fuse possible > that could have been blown or another cheap part that can be replaced? there is a fusable link that may be the source of your dismay -- is located under the hood near the battery -- looks like a pink/redish 12 gauge wire -- says "fuse" or poheps "Fusable Link" > Initially I was able to jump it with the jumper after I bought it, but > haven't been able to since she hooked it up to the AC. ??
