Wiring help
Hey guys i've got a little problem. i would of put this in the elec. form but it doesn't get alot of traffic. My batterey kept dying on me so i took it to schucks and had it tested along with my alternator. they both checked out good to go. They said that i could bring the truck down and they could check them both in the pick-up while it's running and try and figure it out from there. So i brought it down and they said that the alt. isn't charging the batterey. Keep in mind that i just got the truck running for the first time since owning it and i'm inept when it comes to electrical. so i'm guessing the alternator isn't hooked up right. I have it hooked up this way http://www.boomspeed.com/bofh1968/ch...ng_diagram.pdf i hope this link works any way i have a voltage regulator because the wiring harness called for one, not cause the alternator needed one. i have no idea if the alt. needs one and i couln't find anyone that could tell me. I know this is long winded but i figured you could use allof the info i had.
thanks ian |

Re: Wiring help
I couldn't get your link to work.
To tell if the alt is internally regulated or externally is simple. What shape is the plug on the alt? If it is square, and the terminals are like this; II then it is an external unit. If the plug is rectangular and the terminals are like this; -- then it is an enternally regulated piece. You can bypass the regulator easily with jumper wires if it is the latter... there are a few threads in the FAQ on this. If it is the formerly described piece, I would either replace the regulator, or upgrade now to the internal unit myself. |

Re: Wiring help
they are like this II. so i guess i need te voltage regulator. it is bran new, so do i have this wired this wrong? i tried the link it worked for me i just had to give it a minute to load. i don't have alot of money and i need to get this fixed before i leave to Iraq early NOV.
Thanks ian |

Re: Wiring help
yep, factory schematics... if you have it wired like that, then double check all your connections, and verify your grounds are good.
It sounds to me like you have a decent grasp on electrical, so forgive this question... is is going dead as you drive it... and not while it is sitting over night, right? |

Re: Wiring help
well today when i drove it to schucks was the first time. i've had it idling in the driveway alot filling the tranie, tuning it and what not... i'll shut it off then it wont start. weather it be later that day or the next when ever the kids give me a few minutes to try LOL
p.s. don't sweat it i'm doing it cause the ones before me did it and there will be someone else how does it after us. |

Re: Wiring help
A couple of things come to mind on this. If you have the alternator wired as per the diagram then You may have bought the wrong regulator, there are two types, one is a two relay type(wrong) and one is a three relay type which is the correct one.
You may not be getting a good ground on the wire from the regulator to the core support. The regulator is mounted on rubber grommets and needs to be well grounded. Other than that you may have an open wire running to the regulator or the alternator and you will have to run a continuity check on all the wires to determine which one is open.

Re: Wiring help
how do i know if i have a two or three relay type of regulator. i had the grounds bolted to the core support i went ou today and sanded the area around it to make sure it was metal to metal. How do i run a continuity test on the wires? i have a multi meter cam i do it with that?

A continuity test is nothing more than setting the voltmeter on OHMS and putting the negative lead on one end of the wire and the positive end on the other and reading near zero on the meter. An open wire will not have any reading or it's called infinity on the meter. Do not read any wire this way that has a voltage on on it or you may damage the meter. Any of the red wires in the circuit will probably be hot so you can check them by using the "volts" setting and touching the red lead on the wire and the black lead to ground. The red wire that connects to the large terminal on the back of the alternator should be hot as well as the red wire on the voltage regulator. They both should be connected to battery power. There's plenty more to this trouble shooting so let us know what you find. Here is a pic of the regulator coils.
