1862 cub checking seat switches

[Mr Bob]

jsoluna. Thank you so much for sending me step by step directions on checking my wiring. Here is what I found.
Black wire had 12+ volts with key switch in start & on.

Had ground on grey wire at all times.

Had 12+ volts on red/white wire with key switch in run position regardless of pto switch position.

Did not get any voltage through brown wire with pto in any position.

Took wiring off pto switch, removed pto switch and checked it out with my OHM meter. Could not get continuity between any terminals. I believe I should Should have gotten continuity between #5 #3 &#4 in run position.

Any further help will be greatly appreciated. Thanks and have a great day.
Bob
PS I have a second 1862 and earlier I swapped out the reverse relay and this did not fix it.

Maybe this will help.

Thank you OAK. I have that diagram but at 87 years of age, I am sometimes not too understanding of things in front of me. Thanks for your help and have a great day,
Bob

Bob,

It's odd that you don't have voltage on the brown wire with the PTO switch in START or ON, I would assume you would have it in START but not ON based on your description of the problem, but I think we can put that aside for the moment.

Let's do another voltage check:

Your PTO switch connector should have 12v+

START: violet, brown, red/white
ON: violet, brown

If you can back prove the connector and test for voltage that would be good. If you do not have continuity in your bench testing between the terminals that correspond to these wire colors, then the switch may be faulty.
