Question about 1999 Ford F150 Regular Cab

1 Answer

Just bought a 1999 f150 pick up. the guy said he was having a charging problem and replaced the battery and altonator. He had a big sterio in it and removed that so right now it has no sterio. He had it put in professionally, so it does have the clips not just cut wires, but we were wondering if this might be a place to start the hunt, or if there is maybe something else that might cause this issue. He did say that the amp was hooked up directly to the battery, which has been removed.( well the amp is removed, the wires are still there) ... any suggestions?? THanks

Start with having the alternator tested ( out of the truck, not just a meter test like Autozone would do ) and have the battery load tested.

Could be the alternator field fuse is blown, this is the 20A fuse in the same block as the mega fuses on the firewall.
Also check the connector at the alternator to make sure it is in good shape, some times the connector will get gummed up.

1999 ford f-150. replaced alt. charged battery started truck 11.5 volts and dropping. within minuets the bat was dead. had new alt checked it was fine. coult the fusable link be bad

I doubt it is the link. The only way to kill a battery that fast is a huge short. Your wires should be smoking. Is the alternator wire shorted? I have some short troubleshooting tips, but I'm not sure they would work on such a big short--it really should be almost obvious. The tips are here: . These are generic instructions. Let me know if you have more questions.

Charging system alt does not chareg in truck. Bench tested O.K.

Measure the voltage at the big wire on the altenator engine off, do you have power? Check in your distribution box under hood, find the two rows of fuses located inside the box on the outer edge, look at the outside row from front to rear the 4th fuse (# 11/ 20 AMP fuse), is for the altenator field, make sure this fuse is not blown, if it is good and you have battery power on the big wire at the altenator, then replace the altenator. Hope this helps, let me know.

How do you check if altenator is charging battery,

Most vehicles if you get the car running and unhook the positive battery cable it will stay running that is because it is running off the alternator. if it dies like your talking about I would most definitely say your alternator needs to be replaced. Most likely when you jumped your father in laws pick up there was a bad ground somewhere and your alternator got a surge of electricity and it fried it. Hope this helps.
