Posted August 6, 200816 yr comment_255481 Okay so im trying to install a Crane XR3000 into my late 260Z and from what I read I need to bypass the ballast resistor. Everything ive found says just run a jumper wire to the two wires on the resistor, but I have three wires on my resistor (the PO did a hack job with the ignition). Can anyone tell me how to bypass my resistor? Thanks Brad Link to comment https://www.classiczcars.com/forums/topic/28928-bypassing-the-ballast-resistor/ Share on other sites More sharing options...
August 6, 200816 yr comment_255484 It looks to me like take the far right wire off it's terminal and connect it to the far left wire terminal. But I'm not that familiar with those so I think I'd wait for one of our experts to chime in. How are things in Tucson? That was my old stomping grounds for 30 years.Steve Link to comment https://www.classiczcars.com/forums/topic/28928-bypassing-the-ballast-resistor/#findComment-255484 Share on other sites More sharing options...
August 6, 200816 yr Author comment_255486 things in Tucson are good we've been getting a lot of rain if you can believe that Link to comment https://www.classiczcars.com/forums/topic/28928-bypassing-the-ballast-resistor/#findComment-255486 Share on other sites More sharing options...
August 7, 200816 yr Author comment_255564 Well im not sure about just moving the left wire to the right wire, first of all the left wire has a positive sign next to it and the right one has a negative sign next to it, and connecting a "+" and a "-" doesn't seem like a good idea and second what do i do with the middle wire?

August 7, 200816 yr comment_255587 Well im not sure about just moving the left wire to the right wire, first of all the left wire has a positive sign next to it and the right one has a negative sign next to it, and connecting a "+" and a "-" doesn't seem like a good idea and second what do i do with the middle wire?The plus side will be battery voltage the negative side has the voltage lowered by the resistor and goes to the coil. By connecting those two together as I proposed you no longer drop the voltage to the coil. AKA bypass the resistor. I would guess that the middle wire has it's voltage dropped by a lesser amount and goes somewhere else. I would leave it alone. Again I'm using general automotive knowledge and not Z specific so I could be missing something.Steve Link to comment https://www.classiczcars.com/forums/topic/28928-bypassing-the-ballast-resistor/#findComment-255587 Share on other sites More sharing options...
August 7, 200816 yr comment_255589 You could just remove the wire that goes from the resistor to the coil and add one back that goes from the coil to the plus side of the resistor if you want to leave everything else alone.Steve Link to comment https://www.classiczcars.com/forums/topic/28928-bypassing-the-ballast-resistor/#findComment-255589 Share on other sites More sharing options...

August 7, 200816 yr Author comment_255604 Okay I found this diagram after an extensive search. I had to modify it a little to illustrate a non fuel injected ignition, but this clears up my questions. Hope this helps anybody who need this info in the future Link to comment https://www.classiczcars.com/forums/topic/28928-bypassing-the-ballast-resistor/#findComment-255604 Share on other sites More sharing options...
August 7, 200816 yr comment_255606 Are you showing the modified one? The negative side of the coil should go to the points. Or do 260's have electronic ignition. In which case you already know you should ignore all my comments.

August 7, 200816 yr Author comment_255612 Well the stock 260s (late anyways) had electronic, but the PO decided to convert to points for some reason, so things are a little differemt Link to comment https://www.classiczcars.com/forums/topic/28928-bypassing-the-ballast-resistor/#findComment-255612 Share on other sites More sharing options...
