Hi All,
well...next problem, aside from this...
Whilst I'm deciding what to do about the above I decided to make sure everything else is ready to go.
Noticed the other day my fans didn't come on when I had the truck running and upto fan operating temp.
I got my multimeter out and measured my outputs from the PCM and they're working fine.
I used the 'force on' part of EFILive (which is fantastic by the way) to turn the fan outputs on and check them.
I get the low speed fan to come on but when I force the high speed fan on the two relays just click on and off like mad.
If I pull the relays and test the voltage across the PCM outputs I have a steady 12 or so volts (about 11.92 as my truck battery is a bit low). If I plug the relay back in, it goes back to clicking on and off.
When I 'force' the outputs on, does it completely overide the settings in the tune? If not, could that be my problem?
On/off delays etc?
