Ford/Bronco FAQs

Question:  I'm seriously considering getting your harness, for my Bronco, but I was reading through a friend's manual for his Centech Harness and I noticed It states that Centech does not recommend one wire alternators. My Bronco alternator is on the way out right now and I was planning on replacing the alternator with something like a 140A one wire unit with an internal regulator from Powermaster.

I was just wondering why you do not recommend one wire units, and if you could point me in the direction of a better alternator to get. I noticed it also mentioned something about the harness being compatible with GM internally regulated alternators. I was wondering if you could clear this up for me because I don't want to jump into anything like this and then be stuck with an alternator I can't use.

If you think that the GM alternator is the way to go, can you direct me to a place that sells these alternators that are compatible with the Ford mounting bracket

Answer:  PowerMaster make a good alternator; however, by design the one wire setup loses voltage as your current requirements go up. This is due to the voltage drop across the wire connecting the alternator to the battery. This is why a wire gets hot as the current through it increases; in fact, if you double the current, the wire will get four times as hot as before.

On standard charging systems, the regulator compensates for the voltage drop across the wire by increasing the voltage output of the alternator by measuring the voltage at the battery to maintain the proper battery voltage. For example, if the battery is normally charging at 13.5 volts and the current requirements increase to where you lose .2 volts, the regulator which is monitoring the battery voltage will increase the voltage from the alternator an additional .2 volts to 13.7 volts. At this time, you will have 13.7 volts at the alternator and 13.5 volts at the battery.

If you intend to use a one wire alternator, use the largest possible wire thickness to reduce the voltage drop (loss). I suggest at least an 8 gauge with the 140 Amp system.

The BR-10A comes with a 10 gauge battery wire for the Ford External regulator alternator normally found in a Bronco. It maybe be best to use a high current version of a Ford alternator by replacing our 10 gauge "battery" wire with a thicker wire and keeping our control wires between the alternator and the external regulator intact. This will eliminate the need for a different alternator mounting bracket (GM Type).

In cases where you're going to run a winch, it would be better to run the 140A alternator to a splitter to charge two batteries. Use the second battery to run the winch etc. while the primary battery supplies our harness. Contact NW Power Products for more info on this equipment

Question:  I'm making a Hot Rod out of a 1979 Pinto Wagon. I'm puting in a 1986 Turbo 4 CYL. out of a Thunderbird Coupe. I plan on taking out the dash and putting in one with more gauges. Now here's the question. Is there anywhere on the net I can find the wiring diagram that'll show me were to connect the wires back to the CPU in the right order to make engine run? Will I be able to get a harness for dash I plan on putting in or will I have to make every connection custom?

Answer:  Go to your Ford dealer and ask for (buy) the ELECTRICAL & VACUUM manual for that 86 T-Bird. This will have the complete schematic.

Question:  I am converting the old point type ingnition system in my 1968 Ford Mustang to a 1978 electronic system. I already have all the parts except the wiring to connect it all together.

Answer:  We don't carry that wiring. You can check at your local library for a wiring diagram. Ask for the MITCHELL MANUAL or a HAYNES manual for that year.
