Hi all,well great to finally meet rog and his lovely ladies (one being a slightly mad cat) tonight and have a good look at the saph cos,cracking motor too.
So we managed to get a good look at this tonight and traced it (so we thought) to a bad ignition amplifier that's housed on the inner wing near the battery.
It showed a dead short from pin 24 to earth which looked wrong in the diagram as it simply terminated at the amp.Tried again with the amp plug off and no blown fuse.put the plug on and tried again,no blown fuse,even tried another one that had been swapped when the fault first came up,no fuse blown.
We've tried wiggling the loom to see if there's any loose connections causing the short but again ok.
Great!!!
Now not so sure?
Tested the other one rog had laying about yet that had the same readings of a near enough dead short between where pin 24 terminates on the amp (think its pin 3) to pin 2 which is the main earth,all wiring resistance values are spot on.
Rog had a look on big turbo.com and after a bit of searching it turns out that it's basically a transistor based amplifier with pin 3 (from 24 in ecu) being a "reference ground".
Now,without wanting to simply diagnose this as a bad component etc which neither of us think is the case I'm wondering if any of the tuners on here/those in the know have any ideas what the resistance values should read between pins on the amp so I can make a good judgement as to whether it's simply bad luck with two dodgy parts etc.
We're gonna bell out all the wiring from the ecu etc to confirm there's no other issues as rog has found a few bits and bobs that aren't ideal and these will be fixed as well but generally the wirings in good order and the components I've tested so far are standing up well to the resistances stated on various websites etc.
So fingers crossed that's all it was but were not 100% convinced yet so let's not close the thread just yet!!!!
