Killed my 2nd ecu in a year

Last year in September, my 90 stopped while driving on normal road.

A week ago during an event I stop the engine to see how someone takes a hill and when restarting, nothing!

Changed the ecu to the standard and it fires up without problems.

Talked with Pete from BAS this weekend and he thinks is a shortcircuit somewhere....

Question is: where to look as I would expect a shortcircuit would happen immediatly again?

Any suggestions?

Easiest but not cheapest route would be to get someone to fault find the ECU to see what has died, that would then allow you to check the wiring that feeds (or is fed from) that functionality of the ECU. Intermittent faults are a bugger to find, the ECU fault is permanent by the sounds of it so I would fault find that.

The most common place for the loom to rub through is where it passes over the transfer box, i've repaired quite a few in this area, if you remove the centre access panel on the seatbox and run your fingers along the wiring feeling for any abrasion you may well find the problem
