Steve Said"Just means that the input and output share a common ground. Should not be a problem, except for this scenario:The ET does not have a chassis ground. So you could have a single wiring fault to chassis and not know it. Now you take the DC-DC and install a cigarette plug on the chassis that connects the negative terminal to the chassis mount. You now have a weird short that will cause odd problems you can't trace easily. Realize this requires two unsuspected things, but most accidents come from two things or more things going wrong."But, Wouldn't' t it be OK if you mounted the inverter on an insulator and thenwired the Lights from the 12Vdc output and then back to the common ground.And Pos 36V input to the invert input and Neg 36V to the common ground?
Yes that's fine. I guess I should have just said it would be prudent to maintain the floating chassis, which you would be doing. I was just trying to caution against a possible scenerio that would cause great consternation. I know I have had (and read of other accounts) experience with a chassis fault that came to be known when I had another fault and VERY strange things started to happen.
Please tell me if I am wrong I don't want sparks and nastiness. (LOL) Because if this is OK it is a worth the effort to keep the pack balanced.I guess the other option is to wire the lights in series and add a tail light. Or find some 36V light bulbs that fit the sockets.Harold I may be dreaming but are the lights on New Ideas 36V?The real issue to me is taping the pack for the lift, I really don't use the lights that often. But, the lift is another thing. Geof Thompson A-60,E-81, ER8-36,R-36 E-8, E-10x2, E-12M,E-12, E15x2,E-20x2, B-145X2, C-185, E-141X2.
