Small bump in the road.
I've been drivin the Blazer every other day and lovin it. One thing though, Ol' Yeller keeps draining the battery. I pulled in today and shut him down and tried to re-start. No dice. Not enought juice to turn it over. Battery is pretty new and it lasted about a week. I guess I should check the alternator first and tape up any loose wires. Any other suggestions?

Re: Small bump in the road.
Does your horn work/not work? It could be your horn drawing the power from the buss bar - even if it isn't wired up to the core support.
That way the battery experiences the draw on the system - but you don't hear the horn to know that it is the culprit... |

Re: Small bump in the road.
You can try to see if you have a key off voltage drain. With the ignition off and the postive battery cable connected to the post. Disconnect the negative battery cable and connect a test light or meter leads between the negative cable and negative post. If the meter shows voltage draw or the light comes on you have a drain somewhere. Otherwise I would say a bad alt not charging since the battery is new.

I took the alt off and I had it tested. No bueno. I bought a new one as well as the voltage regulator. Installed both and charged the battery and it fired right up. Went to my uncles house about 20 miles away w/o any problems. HOWEVER, on the way home I noticed my brake pedal get lower and lower. By the time I got home it was going all the way to the floor and the brake light in the dash was on. I got home and cracked open the master cylinder and the front reservior (sp) was empty. S.O.B.!!!! I just had the brakes done. Gonna have to call my buddies at A plus automotive and take them Ol' yeller. Oh yeah, I only have one headlight too. I already replaced the foot switch and still one light. Any suggestions?

Re: Small bump in the road.
Check the terminals and the ground on your headlight. After almost 40 years, wiring tends to corrode or just break.

 What he said! Also the old connectors to the back of the light can get pretty sloppy or even burnt.
