I had unhooked the battery to test the alternator. I accidentally forgot to hook the terminal back up. Gen light came on just before it stalled. It won't crank now.

Mechanic's Assistant: Have you checked the fuel supply? And are all the spark plugs working?

I just got it today. Fuel shows quarter tank. Battery shows decent voltage when key is turned on. It will need a tune up.

Mechanic's Assistant: What is the model/year of your Dodge?

1997 dodge ram 2500

Mechanic's Assistant: Are you fixing your Ram yourself? What have you tried so far?

Yes. I tried hooking battery back up and seeing if it would start. I don't have any type of testers.

I didn't realize It was unhooked until it died.

okay go to the fuse and relay box under the hood and check the main fuses ,well best check all fuses .

Hook up the battery and check the battery voltage with the ignition switched off .

Why was you checking the alternator removing the cable ? to see if it stalls .doing this can cause

ECM malfunctions .

Ask Your Own Car Question

First we need to see if we have a fully charged battery ,a full charged battery will have 12.6 volts .

if 12.2 or lower you will need to charge up the battery .
