Re: TR delco Alt. upgrade not working ???
Boy, you is lucky the fat man is on tonight...
Check out the graphic, it's self explanatory.
Don't over think this thing, it's not rocket science.
Make sure the ground of the light socket you used is ISOLATED, meaning it can't get any ground except through a wire.
This is the most common mistake.
The second most common mistake is to use too small of a bulb. If you think that might be the problem, you can use a 1 watt-150 ohm resistor inline with the light socket. Doesn't matter which side you wire it into, it's just there to add resistance.
Radio Shack should have them for under a buck.
The next most common mistake is not to ground the alternator case to the battery.
The third most common mistake is the connection of the two wire connector.
If you draw the power for the #1 wire from the ignition coil circuit, make sure you use a DIODE (Two bucks from Radio Shack) in the line so the vehicle doesn't run on after you turn the key off.
Just use a Key switched feed that is off when the key is off, and on when the key is in the 'RUN' position.
If you put the diode in, and the vehicle runs on after you turn the key off, Turn the diode around, you have it backwards.
Make sure you hook the #2 wire to the horn relay 'Hot' side.
That is the way your alternator knows what current all of your accessories are using up.
The horn is after the fuse block, and all of your accessories, so it gives an accurate accounting of the current being used.
Most people like to hook it to the back of the alternator or the battery.
You should already know what the battery and alternator output is via the volt gage...
The fourth most common mistake made is to hook the 'BATT' wire straight to the battery with out a fusible link.... Or even with a fusible link.
UNDER NO CIRCUMSTANCES SHOULD THE ALTERNATOR BE WIRED DIRECTLY TO THE BATTERY.
With the fusible link hooked to the battery side of the starter solenoid, you have a good, solid electrical connection, and you have a safe distance from the battery's explosive gasses incase the fusible link burns violently. (Another good reason to use a fusible link, to keep your vehicle from burning down!)
