Agreed, make sure your ground is good.

Best way to do this is:

1. Take a 10- 14 ft piece of wire (depends on how far away battery is) and measure the resistance (ohms) of the wire. (Grab a DMM and put red lead on one side, black on other. Set to ohms)

2. Remember this #

3. Take and connect one side of the wire to the neg terminal on the battery.

4. Take Red lead and connect it to the spot you believe is a good ground.

5. Take black lead and connect it to the long wire running to the battery. (You are making an extension for your meter)

6. Take the reading your DMM gives you and subtract the wires resistance from it. It should be under 1 ohm.

Ex. Wire Resistance = 1.4 ohms.

Ground reading on meter (w/ wire resistance) = 2.6 ohms.

2.6 - 1.4 = 1.2 ohms.

TRY ANOTHER SPOT.

Ex 2. Wire Resistance = 1.4 ohms

Ground reading on meter = 2.1 ohms

2.1 - 1.4 = .7 ohms

tried everything you guys mentioned. problem still persists.
