1989 f350alternator problems
 

i have a 1989 f-350 with a 460 gas injected engine . i recently changed the batt cables the starter solenoid and batt .the amp meter is real slow to react re-when starting it will show discharge for some time and then real slowly move up to charge if you turn the jheadlights on it will go to discharge and slowly go back to charge after turning them off it is the same way with the heater blower . any body got any suggestions for a remedy?

Best suggestion would be to find the appropriate forum. You posted this in the 2009+ truck section.

Scan down a bit and you will find what you are looking for. :D

Welcome to FTE 1968trailboss :)

I've moved your question to a more appropriate forum for you.
The guys here should be able to help.

standard problem with these year trucks. the gauge sticks in the off position. once started, give the top of the dash a smack rite above the volt gauge. the gauge should pop rite up to charge.

Use a digital volt meter and measure what the voltage is at the battery with the engine off. It should be 12.6 to 12.9 volts DC. Start the engine. The voltage should jump up to 13.6 volts or better. The alternator is designed to produce enough to keep the voltage at this level with all of the electrical on.
Happy New Year
