[QUOTE="smoka, post: 6279869, member: 606721"] In your case if you want to test the ground, you would need to remove one of the batts. If you want to test the front grounds, then remove your front batt. If you want to test your back ground, then remove your back batt. With batts on both ends it will be harder to test. With 2 batts and an alt, it would be really hard to estimate the current travelling through your grounds at any given moment. So by removing one batt, you will have a longer power/ground loop to test with. I've never really thought about testing the front grounds, usually its the back ground locations that can be tricky. You said you have a 1/0 ground wire ran to the back? Is it also connected to the frame at both ends? If you said yes to both its really unlikely you need to test your frame ground points because even if they are bad then the current would run through the wire which should not cause much of a voltage drop unless the wire is corroded or connections are messed up.
