    JLG 45ic Electrical Problems

    Ok will do. The schematic has two numbers for that relay 848/849, I am guessing I need the 849 (#4460375). I have sent an email to www.epwparts.com to see if they have that part. They are not showing that part on their site. Thanks for the help.

    JLG 45ic Electrical Problems

    I cut the blk/white wire 86 and grounded it to the relay bracket, still wouldn't start. When I jump 87 and 30 it starts up. Does that mean relay or ignition processor? I managed to get the relay apart and exposed the relay coil, which was a job in itself. I am going to go back through some of...

    JLG 45ic Electrical Problems

    Yes, the relay looked like it was sealed, I will cut the black/white wire 86 and ground it. I found the start relay lying in the engine tray, it looked like the metal clip that holds the relay to the relay bracket has been broken off for some time. Do you think the relay gets ground from that...

    JLG 45ic Electrical Problems

    I found the fuel pump relay, 30 was hot while cranking, 87 wasn't hot while cranking, I jumped 87 to 30 and it crank and ran fine. I couldn't figure out how to pull 86 out of the harness easily so i didn't ground 86, do I need to or can I assume this is a bad relay?

    JLG 45ic Electrical Problems

    I checked the new coil i installed and everything looks correct. I pulled the fuel line off of the pump and now it is not trying to pump gas when i turn the engine over. It was pumping gas earlier, should i replace the 87A fuel relay(s)?

    JLG 45ic Electrical Problems

    Thanks ATCO, prior to my problems in getting the lift to crank i had a bad coil on cylinder 2, I replaced that coil with a new one. I started it after i replaced it and thought ok that worked fine. It ran good then it shut off kind of sudden, i thought it had run out of fuel. Now after reading...

    JLG 45ic Electrical Problems

    Thanks for the information, I have checked the dual fuel switch and it is in the gas mode, but now that you say that it has me wondering if something has malfunctioned with that switch (because i have flipped it a time or two). I thought the pump would have power to it with the key in the on...

    JLG 45ic Electrical Problems

    My JLG lift is not supplying fuel when i turn the key to the on position. I applied 12v to the fuel pump and it works, checked the fuel shut-off solenoid with 9v and the plunger moves. Could this be a bad relay somewhere? Any help would be appreciated.
