so i just got my 4514 all back together runs good . had my combination relay rebuilt by tom . the only thing is the parking brake light is always on even if i unplug the switch anybody got any idea what it is ?

I will guess that with the parking brake light always on, there may still be a problem with the combination relay. The combination relay will prevent a start if the brake switch and light are off. It will also turn on the alarm buzzer if you engage the transmission and try to move with the switch and light on. At first I thought a wire from the parking brake switch may have gotten pinched and grounded, but if that happened you would still have the alarm when trying to move.

you may have a bad switch, you cannot just unplug it. with it unplugged, ground the blue and black wire.

 

[hvychevy20]

ok thanks tom i will try that today

 

[hvychevy20]

ok so i unplugged the switch and grounded the blue and black wires on the wire harness side all the way to the battery still the light is on any other ideas?

how many fuses does your tractor have, 3 or 4?
with park switch unplugged on later models everything should be dead, no lights no starter etc. does the buzzer sound when you try to put it in gear? does it start and run? plug switch back in and does buzzer sound with brake on when put in gear?

 

[hvychevy20]

my alarm is not hooked up so i cant tell on that part. mine has 3 fuses . the tractor runs fine just the light is on

 

[Tom Bauer]

unplug relay and see if light goes out? with key on one side of bulb gets power, relay grounds other side to make it come on.

 

[hvychevy20]

ok just went out and did as you said and yes with the relay unpluged the light does go out .

 

[Tom Bauer]

ok, well send it back and i will see what i can do?

 

[hvychevy20]

Thank you sir . i guess i should add none of the other dash lights come on i had heard that they should all come on for a sec when u first turn the key but im not sure if thats right . can you pm your address so i can send it out this week

 

[Tom Bauer]

strangely, only the first series of 4514, up to serial 1006846 had bulb test, then when they did away with the fuel module they also did away with that.

 

[hvychevy20]

ok sounds good . i will send out this week if you can send me your address

hi Tom, I just repaired my grandfather's 4514 as it had a bad ignition coil. I'm now on to my next problem which seems to be a similar issue as you described. When releasing the parking brake and engaging the transmission to go forward, the buzzer comes on. I have a temporary fix to unplug the buzzer but I'm looking for a solution to fix it. Any thoughts? I'm thinking it's a bad park brake sensor or something shorted in the combination relay of wiring in general....
