gt-14

[boatman 3]

:)

I have a 1969 gt-14. The engine has the pointless ignition system.

It is not charging. I believe it has the 10 amp stator. I have changed the

rectifier and it didn,t help. Can some one tell me how to check the stator

and also the rectifter. My rectifier has all 3 prongs in a row. :WRS:

Two of the three lugs on the rectifier / regulator will be marked "AC"

Disconnect the stator wires from these lugs and set your multimeter to measure AC VOLTS

with the tractor running near full speed, you should read at least 28 VAC or higher from the stator wires.

if the readings are jumpy or erratic, the stator wiring or terminals may be corroded and need to be cleaned or replaced.

:WRS: Hi Chuck,

Thanks for info I will ck it out. :hide:

:hide: Hi All, checked voltage from stator wires and I am getting

25 to 27 volts ac. Only getting .3 amps out of regulator. Might not be

the right regulator. I bought this reg off ebay. It doesn,t have any

numbers on it. Old one is a repco fg-4720 b. my stator should put out

10 amps. Looked up regulator on a kohler web site and they want $360.00

for it. Anybody know if something else will work?

Only getting .3 amps out of regulator.

are you measuring AMPS from the regulator to the battery?

If so , this is not necessarily a bad regulator. A .3 AMP charge current could be correct for a fully charged battery.

Try to measure VOLTS across the battery.

Take 2 readings - one with the engine off and a second reading with the engine running full speed.

Somewhere in the range of 12. 5 to 12.6 volts with the engine turned off should be seen for a good battery. The voltage should increase to above 13.8 when the tractor is running full speed. A voltage over 15 should be considered as overcharging.

Take the two readings and let us know.

sort of on the same topic of this... my GT14 has AC voltage from the stator but nothing from the regulator, i have a regulator from a bronco 14 that uses the 3 prong block plug (not in line) could i try this regulator and see if that works?

this should not be any problem Justin.

Just be sure

1/ the stator leads get connected to the terminals marked "AC" on the regulator.

2/ "B+" terminal is connected to the tractors electrical system

3/ the case of the regulator is connected to a clean , known good chassis ground.

:hide: Hi all, I finally found after market voltage regulator rectifier

for $89.00. Alot better than the $337.00 kohler wanted for the part.

Will let you all know how it works when I get it. It looks alot different

than the original part. It is for the 10 amp system which is what is on my

gt-14. My other option was to drive a small delco single wire hookup

car altenator off the fly wheel side of eng. using the old starter /gen

pulley on flywheel.

Beautiful!!!!! I just ran in charging problems on my C120 and have swapped the Regulator/ran seperate grounds and got it to work then not then on and such... I was looking for how to test the rectifier and this diagram is the Cats meow..... THANKS SOI

Just to say what fantastic illustration of detail show by (save old Iron ) on how to test and solve an Electrical problem, .

I would never understand how to set up a test like SOI has shown until i saw his presentation.

SOI , Your information & knowledge & willing to help people here on redsquare is invaluable , Im sure i will need you help in the future so i take this oportunity to thank you in advance. .Thank you & its a massive asset to have you here at redsqure .
