Re: Voltage Regulator tech help
You can purchase new fusable link wire if you like. You can use fuses.
You might be surprised by the fit of a CS130 with your surpentine system. It might bolt right up. The original 67 / 68 alternator mounting was slightly weird. The OEM heads didn't have holes in the front so that bracket in the tech reference was invented later, but happens to line up with the short waterpump setup. With your aftermarket bracket, hopefully everything will plug and play for you. Long vs. Short water pump configuration is the only gotcha you need to comprehend - and it's not that big of a gotcha when you have ALL the brackets.
The CS-130 alternator (as do others) come in different "clock positions". The clock position refers to the location of the mounting tabs. If you got an alternator with the right orientation for your brackets, I suspect it'll work fine. You might want to call your bracket supplier for advice. On my 68 with a short water pump using the bracket in Wes' article, I used an 8' oclock orientation. I believe I may have separated the case and turned in though. I remember the part number was incredibly simple like 12345 or similar. I'll see if I can find it.
I won't bore you with remote sensing other than comparing it to a garden hose. Suppose you have really long garden hose and you can't get the pressure you need out of it. Remote sensing would be like a pressure sensor (a wire) that can open the faucet up more to give you the pressure you want at the end of the hose. Remote sensing compensates for resistance losses between the alternator and the battery.
I would probably advise you to start simple and do the wire shorting technique described in Wes' article if you use an internally regulated alternator. (I personally haven't done it so I can't confirm the wire colors -- I'd just trust the article since many guys have used it). It's something you can do in less than an hour and verify that it works as expected. You can always switch it later.
If you do adopt an SI or CS style alternator, up-size the wire between the alternator and the horn relay (or battery junction if you decide to to the remote sensing thing).
