Re: M&H front lighting wiring harness w/ alt conversion

ChevLoRay,

Thanks for your comment. I think you're right and I'll just have to get a longer alternator housing bolt and build a spacer to mount the bracket. I guess I just assumed that M & H had this all factored in when they designed the harness with the internal regulator wiring modifications and the bracket they supply was intended to mount in a specific location on an internally regulated alternator. It's obvious to me now that the original regulator has an entirely different housing design and rear configuration. If I come up with some "slick" way to do this I'll be sure and post it for all. Thanks again!

Monty

Re: M&H front lighting wiring harness w/ alt conversion

Look, you shouldn't have to open the alternator case. Just hack off the last half inch of the ground bracket and forget about it.
I'm surprised that there isn't some crevice the angle end falls into, but if not it's no big thing.

68OrangeSunshine,

I'm not going to open up the case. I'll figure out a way to mount the bracket even of it means cutting or modifying it somehow. I'll post a pic when I get it done. Thanks again!

Monty

Re: M&H front lighting wiring harness w/ alt conversion

To all,

I went ahead and modified the ground bracket to attached to the newer style alternator w/ internal regulator. Below are some pictures of what I did. Let me know what you think and thanks again, everyone, for your comments.

Re: M&H front lighting wiring harness w/ alt conversion

I gonna try and post some pix. Shots of real Delcotrons in actual running trucks.

One view from under the 4Bbl carb, on an L6 [stock wiring, with HELP reapair bits as necessary...] ('68-C/10).

Other view is on '71 GMC w/ V8 and M&H product harness.

Another shot of the 292, from side.

.
Guess I'll have to hotsplice the pix off the digiccam again>
Dang this newfangled X#$%$^^

[Edit: upload failed. I'll try later.]

Re: M&H front lighting wiring harness w/ alt conversion

Here is a pic that identifoes alternators. The second from the left matches the one posted. It appears to be a 75 to 84 internal regulated model and the harness you show has been modified for the conversion.
This stuff ain't rocket science, I agree with chevloray, just modify the bracket to fit. Unless you are trying for a 1000 point concours restoration, who cares as long as it works.

Re: M&H front lighting wiring harness w/ alt conversion

The SI alternator is the one M&H likes so they make all their harness to work on it. They say it's the longest lasting and is better performing too. I had a brand new CS sitting in the box for years so that's what I'm going to use. I had them make an adaptor, apparently all the SC only need one wire. While the SI needs two.

You will like the CS and it does only require one wire unless you count the output wire to the battery.The feed wire from the large terminal. Here is a great site on them. Page two applies to your post and tells how to wire the alternator.

I’ve been looking for that info! I went to 2 different alternator shops and got 2 different answers on how to hook this up!
Thanks,
