Bit of update
so while on the dyno we discovered a few drops of oil under the car. A bit of investigation reveals the most likely culprit is a cam seal…. Annoying! So at some point I’ll have to pull the front of the engine off and install a new seal.
I’ve also been speaking to Brett at BDE and will be purchasing his now PS pulley for ATi crank pulley, which will resolve the issue of it spitting off its PS belt.
I’ve also been going through the datalogs of some of the drives I’ve had to identify the cause of the imbalance of fuelling between banks. While I’m not sure it’s totally the cause, I have found that the alternator is not keeping up with demand. While the pic shows voltage drop during a pull down to 13.06v, wider analysis identifies a direct correlation between the fuelling of the engine and the electrical systems being above or below 13.5v. So I’m going to have my alternator inspected, and if it’s performing as expected I’ll either look at having it uprated to 120amp (to offset the 24amp draw of the 525lph pump) or if that’s not possible I’ll look to upgrade to a 200amp unit from WPS or WOSP.

Help / advice needed
I own a 300ZX fairlady N/A manual
Battery keeps going flat.
Several times when I jump start it the headlights are on despite the switch being in the OFF position - which I presume is causing the battery drain.
I presume it is a faulty swtch.
Today the alarm was going off repeatedly and I couldn't stop it with the remote - offside headlight was on brightly, nearside was on faintly.
Not sure of the cause.
Have any other members had similar problems.
Any assistance would be appreciated
Thanks
