am i the only one that noticed he has a 200 amp alt and a redtop battery up front and he is only running about 500wrms???
^^^^either way, BOTH batteries HAVE to be grounded out to chassis. Regardless of whether or not the flow of electricity goes from battery #1 to chassis or to battery #2, it will STILL have to go to chassis eventually.For the OP's level of power, a chassis ground on the back battery is fine.
However, there have been tests that have shown that a piece of 1/0 wire is MORE conductive than the chassis of a car, which is made of steel (which is FAR less conductive than copper) and lots of welds.
If you plan on running big power, grounds to the front battery/alternator(s) is a must.
please elaborate....you seem to know some sort of dc wiring i have never heard of^^^^either way, BOTH batteries HAVE to be grounded out to chassis. Regardless of whether or not the flow of electricity goes from battery #1 to chassis or to battery #2, it will STILL have to go to chassis eventually.
When you take a look at high power applications, most guys will ground the rear batteries to the chassis then have 1-2 runs of 1/0 to the front battery and alternator. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif^^^^either way, BOTH batteries HAVE to be grounded out to chassis.

what i was getting at was he was saying it wouldnt work at all without a chasis ground.When you take a look at high power applications, most guys will ground the rear batteries to the chassis then have 1-2 runs of 1/0 to the front battery and alternator. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
When it comes to electrical, if it's worth doing, it's worth OVER-doing.
But to be technical, you don't HAVE to ground the rear battery to the chassis as long as you have it sufficiently grounded to the front battery (which is grounded to the chassis and engine).
He does make it sound like that, however I'm not sure if that's what he's saying.what i was getting at was he was saying it wouldnt work at all without a chasis ground.
