    L3240 won't start when cold... Help!

    Yes, 5 more year until I can retire. I am still tracing the ground no luck yet. I have run another ground to the relay and it works fine now until I can find the main cause and the wife will now be able to run it when I am working. Thanks again everyone and have a happy and safe Christmas...

    L3240 won't start when cold... Help!

    Sorry for the delay again. I did have a second to trouble shoot some more and found, when I ran another ground to the rely, it clicked, activated and was able to start in the cold like normal. So there is something a miss on the ground side that I need to track down. Only has a short time...

    L3240 won't start when cold... Help!

    Hi Everyone, Sorry I had to work 6 out of 7 days straight this week and that is 24 hour shifts, so I didn't have chance until today to get back. I am unable to find any breaks in the wire so far. I did make some "extender wires" with male and female spades to get the replay up out of the...

    L3240 won't start when cold... Help!

    Yes, I just made it out of wire. I am back to work for the next 48 hours, so I will try again and see if I can get the relay socket off for a better look at the connections I assumed pin 4 is ground? I will try and trace it back as well. Thanks again sir, have a great night.

    L3240 won't start when cold... Help!

    Sir, I just wet back out and verified, I do in fact have 12 volt to the wire going to the bus bar/glow plug when I jump the relay socket with a wire. Also with the key on I have 12 volt at terminal #3 I did attempt to move/loosen the dash cluster to get better access to the relay sockets but...

    L3240 won't start when cold... Help!

    Sorry I missed your last question: When I disconnect the wire that feeds the bus bar/1st glow plug, I get no voltage at all when the key is turned to on/glow plug position.

    L3240 won't start when cold... Help!

    Sorry I had to run yesterday, my son had 4H things we had to do. 200mph- Thanks for the pictures I did miss those fuses until I took off the grill but they are all good (there are 2 50amp and 2 80amp) I also checked resistance on the temp sensor with it off and meter didn't change, but I...

    L3240 won't start when cold... Help!

    Also I tested the temp sensor: Unplugged the sensor plug and got good continuity and then with the key in the on position I got 4.8 volts in the plug Tested the sensor it self and no change on the meter/no continuity. Hope that helps.

    L3240 won't start when cold... Help!

    200mph..... I checked again and the fuse at my battery is 80Am and good. At the relay plug I have a red/black wire going into that has 12 volt all the time and a black/red wire leaving the plug and going to the glow plugs. ( When I jump these 2 with a piece of wire and cycle the glow plugs it...

    L3240 won't start when cold... Help!

    WOW 200mph....making my head hurt! So again I am not a meter wiz but I unhooked the sensor and there are 2 small prongs, I put the meter on resistance and the meter never changed, if I did it correctly. Could I jump the plug side just to see if it would start or would that be a bad idea...

    L3240 won't start when cold... Help!

    Hello all, So after following post #3 here is what I found. Under glow plug lead terminal voltage: I took the wire lead off (only wire- that went to the 1st glow plug and also a bar that connected the other plugs together) and got no reading with the switch off, then turned to ON (glow plug...

    L3240 won't start when cold... Help!

    Thanks guys, So I got the meter out ( I am a novice with it) and check the relay. With the key off I get 12V to one leg, with the key in glow plug position I get 12V on 2 legs. Both replays are OEM, I swapped them and put the meter on both relay plugs and get the same results. I get the...

    HI, Thanks for the help. I have a 2010 L3240-HST-3 and this is the first issue I have had with it and need some help. So when the temp's dropped this season it began to give me issues with starting in the cold. I did some internet search and found some starting ideas to check but now I am...
