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?
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
