Hello Sir, My name is ***** ***** welcome back to Just Answer! Can you please start by answering a couple more questions.

What size of amperage is the alternator on your unit and have you ever replaced it?

How many Amps is the inverter you have installed and what do you run off that inverter?

How many batteries are run for your truck and is the inverter installed directly to these batteries?

Unfortunately there is no amperage adjustment so there is a defect present if you did not encounter this previously.

Thank you,

My Truck was out of town but I have the answers to your question.
The alternator is supposed to originally be100 amps according to the manufacturer. I believe it still is.
The inverter is a 5000 watt 12V DC to 120 AC out
Originally the truck had 2 Batteries, I added a 3rd. Now 3batteries

Thank you for the follow up! Before doing anything I would just confirm with a voltage meter that the voltage is dropping at the alternator besides the voltage gage in the cab. Just a warning because I had had those gages do some weird things and it be a false alarm. Only other thing I would recommend checking is the connections at the alternator aren't badly corroded, or a loose ground wire to the alternator, or battery.

If the alternator is not keeping up to 14.1 V while running then it is definitely defective. For your truck I would recommend a 140, or even a 160 amp alternator if it is available.

If you have any other questions please let me know! otherwise, I would appreciate a rating on my service provided.

Thank you,
