Why are my Glow relays not working properly?
The glow relay problems can result from a number of issues but most common are …….. 1. A burnt out glow plug. 2. A bad connection of supply lead to the bus-bar or plugs themselves. 3. Fusible link gone between battery and glow relays. 4. Engine Temp sensor near No.1 glow plug NFG or a bad connection. 5.
What happens when the glow plugs fail on a diesel engine?
Hard starting. Unlike gasoline engines, which use a spark to ignite the fuel mixture, diesel engines rely solely on cylinder pressures to ignite the diesel fuel mixture. If the glow plugs fail, the engine will have to overcome additional pressure in order to ignite the mixture, which may result in hard starting.
How do you test the glow relay on a Mitsubishi 4×4?
Test between the bus-bar and block, you should get a bright light for a few seconds, when turning the ignition on with the engine cold. Post start, the test lamp will turn on and off a few times. Remove the bus-bar from the plugs and connect one crocodile clip of lamp to top of a plug and the other clip to the battery positive terminal.
How do you connect glowplugs to the relay?
the wiring has to be worked out as it varies from relay to replay, try to get hold of the glowplug relay and wiring from the donor Discovery. Connection is very simple. Of the two heavy leads, the brown goes to the battery connection on the back of the starter solenoid, the black/yellow wire connects to the glowplugs.
