Hi thanks for the help. Just purchesed a 98 pulse ambulance.
I have tried the above with no luck with the d5 in my pulse ambulance, my heater starts up and will run continuously when the dial is turned to the blue spot, however when turned to the red section of the dial the heater blows for 20 seconds and then trips out, ie causes the switch to jump to the out / off position.
The heater was tried to be started more times than 4 so has probably been locked out and this may have been due to low fuel as only had 1/8 th of a tank but upon refilling and trying the above mentioned trick no luck!
Any suggestions would be great!
Cheers
