I've got a basket case mustang here, alternator not charging. Someone cut off some wiring in the engine bay that went to the dash, no battery light on the dash and the alternator was not charging. Some simple wiring repairs had it charging again.

Thank you!! You helped me solve my charging issue with my 97 f150, 4.6 liter. I bypassed the tiny bulb in the instrument cluster and now getting charge to the battery, however, now the check engine light is on and the instrument cluster doesn't light up. I will eventually replace the little bulb in the cluster and see what changes. Big help!!

Thank you so much for your video sir. Im shane from philippines. 2days ago i buy a surplus cluster gauge panel. The owner said it is working. So i replace mine with that. After that my battery is nit charging just today i let the electrician check and says ny batt is good the problem is the alternator. So i go home park my truck outside the gate. When im going to park it inside my truck wont start. So i charge the batt for 5mins and start it and put my truck inside my garage. I almost order new battery on it . When im lying in my bed i search on youtube and watch your video. After watching i run in my truck and replace my surplus to my old one and check it. Now its charging. You save from wrong doing of mine.

@JLemley1960 2 жыл бұрын

As to the issue of the corrosion problem, I'm a stickler for ALWAYS applying a bit of DiElectric Grease inside any and every electrical connection, regardless of the location. As an application to the sparkplug boot (either end), it eases later removal and can resist water intrusion. For electrical connections, it can greatly reduce or even prevent corrosion due to temperature and humidity, as well as rain and snow (salt spray) exposure as well. Before reinstalling replacement bulbs, I make sure to thoroughly clean the socket and terminals to remove any contaminants/corrosion and apply a fair amount to the inside base and sides of the socket before inserting a new bulb. Be careful to avoid getting the grease anywhere except the base area of the bulb, because it will most likely cause either an immediate failure, or failing that, can prevent proper cooling of the bulb which will likely also reduce the "lifetime" of the bulb. One other common failure (and often THE MOST common), is a bad or missing ground. You can get "universal" braided-type ground straps from any automotive or "tractor/farm supply" store, and simply connect one from an unused threaded bolt hole and connect 1) Engine to Firewall, 2) Engine to Frame and 3) NEG (-) Bat terminal to either Engine (Preferred) or Frame. With today's modern computer controls, A/C systems, "Power Everything" and all our "toys" (cell phone, tablets, GPS, Radar Detectors, etc), it doesn't take much to overexert older wiring that may not have taken these factors into consideration, on the "drawing board". The upside to using the "braided" strap-type cable, is no insulation to worry about charring/burning (therefore smoking) and it's a fairly cheap/easy/painless install/addition that doesn't require a wiring diagram or deep electrical knowledge. The one thing I would recommend, I always use "star-type" lock washers on both sides of the terminal ends. I will look for a fairly easily accessible location, give the metal surface a good scrape with a tool like a gasket scraper (clean grease/mud maybe scratch some paint), and the "tar washer" will bite into the metal of the bolt and engine/firewall/frame to give a good "metal-to-metal" connection. Again, as with any other "connection", I use a dab of "DiElectric Grease" on the metal surfaces before I make the cable installation (after cleaning/scraping) to deter possible corrosion. Hopefully I've give some useful info. Blessing to All🙏🙏🙏

First it needs to have the voltage checked to make sure that it's charging like it should, beyond that I have seen a few vehicles (usually Fords) that will charge but the light stays on because the aftermarket alternator used a defective or incorrect regulator making the computer believe there was a problem. The dying problem is most likely a result of the computer needing to relearn it's idle setting since the battery was most likely unhooked for the alt. replacement.

If you have a rebuilder around they can install a new regulator, usually not a huge deal on a non-computerized alternator.

@@bulldogsautomotiveadventur4387 the battery light does not come on on the dash idk what’s causing that..

Early BMWs did this as well, the exciter circuit runs through the battery indicator light on the instrument cluster. Did the same thing - bought a new battery, bought a reman'd alternator ... car runs on battery only and dies when the battery is drained. 'EV' of the wrong sort.

It runs up front, across in front of the rad, then back along the bottom of the battery to a four terminal plug around the stater solenoid before running back into the firewall. For some reason the horn wire runs in the same harness.
