My Truma fire front fell off on our last outing, I know the theory of refitting it,
but the fire front doesn't accept that I know!
The Gas/Ignition rod has two long stiff piano wires curled into an 8mm loop
at both ends, both these wires were bent at an angle not straight as shown
in the Truma parts list, I have straightened them. The fire front picks up on two
notched lugs an inch or two up the frame that the front attaches to, then pushes
back onto a pair of wire hooks (after you have threaded the ignition rod through
the cover) Should these wires be straight (horizontal) or as mine are bent downward?
My cover looks fine but as I go to leave the Troll it drops 'orf!
I have considered, screwing it on but I would rather fix it so it works as intended,

If you pull the ignition lead off the back of the ignition module,
you will hear it spark at the module when you turn the gas tap

If you pull off the plug connection which connects the two wires
to the micro-switch in the gas valve, you can short out the two
corresponding pins on the module, this will show if it's the module
at fault or the micro-switch is not working.

I've watched my mobile tech guy refit the front and it always fits right first time. There must be a technique but I'm blowed if I know it.

Wire hooks need adjusted up so they grip the front when its in place trial and error till its correct

JnsE is not very contactable Roger, I did as permission to use his diagrams,but have had no reply.
Brian has them as they were to do with his electrical breakdown.
