Question about 1984 Ford F 150
This really has nothing to do with an F150, but I needed a model to ask question. Liked a few of your answers to other stumped mechanics problems and so thought I'd ask you.
I'm building a custom jalopy and using an alternator I got in a pallet at a auction. 14v, new rebuilt bosch, internal regulator, but no model or serial numbers to look up.
This is what I have:
"B+" post connection (to battery, yse or no?)
"D+" blade connection (to switch - but? don't I need to go thru an Alt. warning light OR VOLTMETER or otherwise?)
"W" blade connection (to tachometer, yes or no?)
That was based on wiring suggestions from someone else.
However, as I've heard I need an indicator light in curciut or or alternator won't charge battery (is that true?), now I am also wondering if I can use a voltmeter instead, and would it wire the same way- that is, via the same route...?
For this car, I primarily just need charging, running only a very few accessories.
I'm sorry for the delay but i'm not coming to this web page as often as before, some people are not too good with the feedback, and we just trying to help for free, well regarding your problem with the bosh alternator as you know the big or thick flat conectors must to have straight batterie power and the you have another smal flat conector and i belive it is called d+ but not sure at this time, any way make sure the big conectors have straight power then while the car is runing conect a regular lught tester the one whit the little bulb inside, conesct it to batterie positive side, and have a votl meter or something to tell you when the car start to charge, then touch the little b+ connector or any samll flat conector behind the alternator, then the cars must start to charge, if it does then you are going to need a batterie light inside the car, in order to have this done well, but if your car do not have one you can get one small bulb soquet like the one some older fords and ge's like in the 80's have on the side fender parking lights and install the bulb, the run one wire to the ignition power, the one has power with the ignition sw in on position, and run the other end to the one you teste behind the alternator, and that must be it, if you have any other questios just send me a message back,i just have not brake fast yet and answering you the best i can. i hope and this help and i will pareciate you feed bakc have a nice day and good luck
