Hi,
Back again.... So wiring - the original alternator/regulator was changed at some point to a 1 wire alternator the old regulator is still on the inner wing and so is the old cable. what can I do with the old cables - trace back and remove them from the loom? There is an issue with the instrument cluster - never managed to get the dash lights to come on or the gen (single wire so I get that now) the oil light never comes on either (indicator warnings work as does the fuel gauge), upon further investigation I found the cables that should go the the temp sender and oil pressure are disconnected. So just to test I shorted them (individually) to ground and checked the dash (with ignition on) just to see if they would work. no luck... I am guessing I am missing a live feed on the cluster side, could this be anything to do with the swap to single wire alternator? I have a couple of pictures added - the dust on the car was right after a dust storm!!!

changing the alternator shouldn't have affected the power to the gauges BUT who knows what some idiot did???
there should be a common positive power wire to those gauges yes shorting the sender end of the wire should have made each gauge go to the max |

I wonder if the previous owner installed the correct sending units for what is in the cluster, makes a difference. The printed circuit plug can be a bear sometimes and can easily be broken or printed circuit "legs" get screwed up with it's removal if not careful. Good luck and hope you get it "figgered" out.

Yeah, It's a Hybrid...It burns gas and tires. No matter how good she looks, somebody, somewhere, is tired of her sh*t. Beauty is skin deep, ugliness goes clear to the bone. |

if you are referring to the GM style 1 wire alternators... just use the large main wire from the ford alt. and put it on the stud on the back of the 1 wire alt.

I think your best bet may be to get a wiring diagram and go through the wiring from top to bottom to see what has been hacked and changed. I am not sure if someone one here has a later model wiring diagram but there is a '73 Torino one on this website. It might be worthwhile to purchase.
This thread has a bunch of information on the gauge clusters. As for the alternator, I'd ditch the one wire myself and either got back to a stock 1G unit or upgrade to a 3G unit. Here is some information for a 1G alternator wiring. It's not too hard to do, and it works reasonably well if you have stock electrical loads. This is the 3G setup, which will allow you to run a much higher electrical load. Best of all the alternators are cheap and plentiful. Read this on a one wire alternator and why they can be a big compromise just to make installation easier (there is a little chart that summarizes the differences) Edited by 72FordGTS - 19-July-2018 at 7:37AM |
