Installation and Testing of the New Relay Circuit
1.
Remove the +12V and 12V GND wires from the terminal block and set aside, ensuring the +12V
does not short to any other metal or wires with some temporary tape as insulation.
2.
Remove both white wires from the interrupter lugs and either cover the ends with tape, or cover them
with shrink tubing. Coil them up and set them aside. They will not be used any more.
3.
Tee off of the 12V wire coming from the
Propane
button. Make sure it is the wire going to the
relighter, not the one coming from the fuse side of the
Propane
button. Smaller gauge wire can go
from this point to one side of the relay’s coil; polarity is unimportant.
(Note: use of an automotive, crimp-type, wire tees is encouraged. Try not to use wire nuts – this
wiring should be treated like any other automotive wiring connections.)
4.
Tee off of the GND lead to the lamp and connect it to the other side of the relay’s coil.
5.
Connect the two “normally open” lugs on the relay to the lugs on the interrupter.
All of the connections on the relay will be carrying small currents, so smaller gauge, vinyl insulated,
16-20 AWG automotive wire is sufficient. Color is not important; exercise your own creativity.
6.
Make sure all connections are insulated, covering with electrical tape if necessary. Fasten the relay to
the top of the fridge with a screw, strap, or glue; a small mound of silicone rubber will also work.
7.
Plug the +12V and GND wires, from the van, back onto the terminal block on the top of the fridge.
8.
Push the
Propane
button on the front panel. The igniter should begin arcing to the burner.
9.
Push and hold the
Safety Valve
button in and watch for the burner to quickly light. Continue to hold
the button in for at least 15 seconds.
10.
Release the
Safety Valve
button and the flame should remain on. If not, recheck your wiring to the
relay.
11.
With the flame burning, blow out the flame and ensure it re-lights automatically. If it doesn’t, the
relight module may be bad.
12.
Push the
OFF
button and ensure the flame goes out and all activity ceases. If this works, you have
successfully completed the fix. If not, thoroughly check the wiring steps above, for the new relay.
13.
Turn
OFF
the external propane tank valve and ensure the gas is off, by trying to light a stove burner.
14.
Remove the van’s 12V wires from the terminal block, setting them aside. (Still got that piece if
insulating tape?)
15.
Disconnect the gas line and pull the fridge out.
