I have a 79 Blazer with a sbc the one in my avatar anyway i took a test light and ran to the + side of the battery and the + side wire going to the starter and the test light is bright..... so i pulled my fuzes one at a time and the light never went out unhooked alt., and checked wires for burns and grounding any ideas im stumped. Pm me if you could asap so i can get it fixed thanks:beerbang:

starter aint shorted so anymore ideas

I'm confused, what is the problem?

since I like guessing games I will try and decifer this thread.

I am guessing that he lost all power and it won't crank? if I am correct then he either blew the fuse link above the starter or he lost the one on the fire wall junction block above the distributor? either one would make him loose system power and still have power to the main wire at the starter.

IF by chance he just has a starter issue then it may be he has insufficient grounds or loss of contact to the body with bad cabling. if that's the case then he should undo and re connect every body ground chassis ground and engine to frame,body and battery. make sure the surfaces are not painted where cables connect. paint is an insulator it carries no current.

IF that is all good then you may have a bad starter. have someone turn the key while you tap on it with a hammer. if it takes off and goes you found your problem.

I'll agree with you, except that I dont like guessing games :sonicjay:

exactly which wire did you touch on the starter? if it is the one on the starter side of the solenoid, then it will light a test light on a good working system, since that terminal will be grounded when the solenoid is de-energized


not exactly easy to diagnose a problem when you dont even know what the problem is suposed to be

it cranks it starts it runs it just DRAINS THE BATTERY and im trying to find out why its not a guessing game i just wanta figure out what is wrong!!

 

[pipepro]

Ok, so does it charge while running? Volt meter across battery terminals while running 14 v+. Or you can try (Engine off all accessories off) pulling off the ground terminal from the battery and then connecting an amp meter in series from the neg post on battery to neg ground cable. Read amp draw. Then proceed to pull fuses one at a time till amp draw drops. Note, some things like radios and alarm systems are always drawing a small amount of current. Give this a try to narrow down your search.

It could be a bad alternator that isn't charging. Another possabilty is simply a bad battery that won't hold a charge. Or, if you have an aftermarket one wire alternator, that could be your constant draw.

 

[Yetti]

I'm glad we are on the right track now.

I am thinking if you have a draw then there can be bad relay, fuse or other thing keeping it on. one of my favorite things to find is stereo wiring that was jumpered into main circuits avoiding fuses and switches. never seems to fail that the problem acures right after an install. if you do have stuff like that under your dash or worse yet main lined to your battery please disconnect what isn't factory. its very hard to diagnose what we know shouldn't be on a circuit.

well thanks guys and as for the radio it was fcuked up i rewired it RIGHT lol and this guy had everything taped together instead of doing it right this guy i bought it off of was a dipshit when it came to wiring but it is charging it has a brand new battery so ill try what pipepro sug thanks guys

Radio's are over rated anyways!!
