hopefully that grabbed someone's beady eye.
I was coming home today, car drove OK then I get a jolt, then trans failsafe
car will shift from auto to sport, but no manual , no other lights.
thought, bugger here we go again,
noticed however the following
at 2k rpm, I got a weird noise from car speakers like a pop or a thud noise
and the instrument cluster kept going a bit dim, then went normal,
hmm, battery or alternator any one ?.
parked up at side of road, wife went to supermarket , and revved car to 3 to 4k . same again speakers popped , then I got what I think was the pcd gong chiming , I thought wife had walked round back of car.. but no. turned car off, and drove home , after a bit same issues
decided I was going to see what my misfire was ( another fault) turned out to be leaking drivers rocker gasket ,. as there was oil in plugs.
took car for test drive, MUCH better drive , a lot more responsive, no gearbox error, put car in reverse, ping there it was again, BUGGER,
so got multimeter out and took some tests here are my findings
this is left after 20 to 30 minutes
ignition off 12.3 V
ignition on 11.9 V
crank 9.98V
idle is 13.2 no load
idle 12.3 load,= lights heated F+R screens
3k RPM 14.2V
settled voltage is 13.3
now the voltage on the battery fluctuates quite a bit aswell,
any ideas any one??
