1986 Mustang GT Dead Battery

So I just got my 86 GT and went to start it up and nothing happened. It didnt click when I turned the key, no lights in the car work and the winshield wipers wont work. I went and got a new battery but the battery cables that are in the car now wont fit the new battery.

So is this a dead battery for sure or could it be something else? And where can I find just battery cables and not a battery relocation kit.

A couple of things:

Beg, borrow, steal a digital multi-tester. Set it on D.C. and check across the pos and neg terminals of the old batt. A fully charged batt is 12.66 V.

If you find the batt voltage low - check the water level in the batt. If low, (top of plates out of the water) -fill to within 1/2 " of the top using distilled or de-mineralized water only. Then try a charge.

Better yet - either take the new batt back and get one that will fit or - change the batt cable terminals, (usually $1.00 ea), so they will fit the new batt. If one cable is too short and the other is too long then you have to get a batt with the pos and neg terminals reversed.

When you get the vehicle started - check across the batt terminals with the meter. It should read 13.8 to 14.4 V, with all accessories ON, if the alternator is working.
