[QUOTE="Jeffdachef, post: 8630446, member: 650438"] yes a bat negative to 2nd batt negative assuming you are adding a 2nd batt. Reason for a dedicated ground is because some cars have a unibody design or some other weird sh*t that prevents it from having a good ground if you just do a chassis ground. That voltage sensor could be like my sienna where it limits idle output and overall voltages just to save fuel. Might need an external regulator if thats actually the case. Dual 1/0 inputs would help a miniscule amount. Not as much as a dedicated ground and 2nd battery does though. A ground from your front batt would be like a direct ground to the alt since you did the big 3. [/QUOTE]
