I'm not sure if they tried jumping the purple wire to the +, but I will find out later today,and if not have them try that..I assume the key doesn;t need to be on for that, I think, as I said , they did measure the voltage in the purple wire while tryingto start it and it was 11.5v..which, as I understand it , is what powers just the solonoid and should be enough for that? I did just go down to the shop and try to start it and interestingly, I discovered that the new battery was completely dead .no int lights or anything,so maybe there is a drain on it somwhere? I jumped to my truck..which has always worked before,but this time nada.. When i turned the key the voltage on the dash gauge did drop by about 4 v and I lasitened closely but I didn't hear any click so does that mean it;s most likely the solonoid(and not the starter itself?) As yousaid Dynomite, I find it odd that the starter would go out just whe the batery was changed(?)

Thanks again

Will figure it out eventualy , I'm sure
One more possibility.....if you continue to try to start the car with low battery voltage there is more of a chance of burning/arcing the solenoid points (solenoid has less magnetic field to engage with full force). Further, once solenoid points are closed there is greater possibility of burning/arcing those points with the starter amrature having not enough torque to rotate the flywheel.

Hot wire the purple with 12.7 volts (full charged battery) and see what happens.

As an aside......I always disconnect my battery negative terminal (terminal easiest to get at with 8mm flex open end ratchet) when I expect to not drive the Z for over a few days (say a week). Even when sitting for several months with battery disconnected, the engine fires right up after reconnecting the battery. The batteries just do NOT discharge significantly by themselves even over a several month period when disconnected.

This applies to my tractors, lawnmowers, ATVs, trucks, cars.....everything with a 12 volt battery. Obviously I have to reset those items where memory is lost by the battery disconnect which are very few (clock and radio selection). I used to mess around with Tenders but got tired of having to leave electricity on just for a tender. I am a minority in this regard on this Forum (actually prolly the only one) just so you know
