Thank you all for your help. I hope all ya Chooks turn into Emus and lay bloody big eggs for ya Brekky. See ya - Gerry

What I have is a simpler, cheaper and overall more foolproof way of reducing the risk of overheating a 300Tdi. than the likes of alarms. A temperature sensitive switch on the head. The wire from ignition switch to fuel solenoid on the injector pump goes through this switch which has spade electrical connectors on it. Contacts in the switch opens if head temperature gets to 105 degrees for whatever reason and motor stops. Also have a bypass switch installed so motor can be run for a short period, eg to drive off road if it stops at an inconvenient time. Best push button, so idiots cannot leave protection switch bypassed.


Have noticed when mentioning this setup on aulro in the past, the reaction is most likely someone will claim this is dangerous because the motor could stop in a situation like in the middle of an intersection. Then someone else will thank them for this "useful" post. Maybe this is influence from vendors selling alarms. I would encourage them to instead consider selling my type of protection, which does need alarms of low water sensors.
