74260ZMan Posted August 6, 2008 Share #1 Posted August 6, 2008 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 Share on other sites More sharing options...
doradox Posted August 6, 2008 Share #2 Posted August 6, 2008 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 Share on other sites More sharing options...
74260ZMan Posted August 6, 2008 Author Share #3 Posted August 6, 2008 things in Tucson are good we've been getting a lot of rain if you can believe that Link to comment Share on other sites More sharing options...
74260ZMan Posted August 7, 2008 Author Share #4 Posted August 7, 2008 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?

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 Share on other sites More sharing options...
doradox Posted August 7, 2008 Share #6 Posted August 7, 2008 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 Share on other sites More sharing options...
74260ZMan Posted August 7, 2008 Author Share #7 Posted August 7, 2008 Thanks Steve ill give that a try Link to comment Share on other sites More sharing options...
74260ZMan Posted August 7, 2008 Author Share #8 Posted August 7, 2008 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 Share on other sites More sharing options...
doradox Posted August 7, 2008 Share #9 Posted August 7, 2008 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. Steve Link to comment Share on other sites More sharing options...
74260ZMan Posted August 7, 2008 Author Share #10 Posted August 7, 2008 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 Share on other sites More sharing options...
