Hya all, just an update, I finally got round to fitting my manual battery isolator and is working fine got 14.2 volts at the dash gauge and drops back to 14 volts, well happy, I removed the original isolator completely and fitted the new isolator where it was , also I managed to get hold of some brake pad securing pins from anything truck. Com, I ordered a week ago Tuesday and they were delivered Saturday morning, and fitted by end of weekend, every thing working OK, and I've booked her in for the test on 1st October
