make sure the cables are both good if they have a spot that feels flimsy the wires inside are likely corroded and the current is not running through it properly. a simple charging system check would be recommended.

Alternator not chargin f350 ford triton 5.4l 2003


Yes, but also look at light relay in Powerbox. Check for power going to brush connector on Alternator and I am told there is a fuse connector about 18-24" from the Alternator.

Ford v10 triton engine alternator won't charge brand new


I had a similar problem on my 98 Tioga (Ford v10). Turnd out to be just a blown fuse in the cab (wich controls the alternator's regulator.) First, confirm its the charging system and not the battery it's self. To do this, start the engine and take a voltage reading at the battery. It should be above 13 volts. If you don't have a tester, with the engine running, disconnect a battery terminal. If the engine stalls, it's proff the alternator is not out putting as it should. Check for a blown or missing fuse. Anything labeled "intrusment cluster" or "Alt" (maybe 14). If the fuses are ok you'll likely need to replace the alternator it's self. On those engines it's not hard to do. Only takes about 20 min and the the alternators are around $130. But defiantly check the fuses first.

make sure all the wires were connected back to the battery there is a red wire that sits by itself and when you disconnect the battery it tends to fall also check the alternator circuit breaker could be blown.

1998 F-150 xlt triton v-8 doesnt charge battary had alternator tested at auto zone tested ok what else could the problen be


If the alternator and the battery are good, the next most likely thing is a bad connection someplace. Remove the battery terminals and clean them up well. Also, try to find your main ground wire, usually bolted to the chassis or engine block, and make sure it's clean. If just one connection is really dirty, the alternator can't get the juice to the battery.
