I'm still working on this Belarus 825 Starting problem.
The 825 still will not start and I'm hoping someone can give me a clue on what to do next.
This tractor was running in the Fall. I found that the relay had blown a fuse. I replaced and cleaned everything up (Battery terminal, copper connections, ground switch connections, etc.) and tried it. The voltage at the Old selonoid was 12V and jumped to 24V when the ignition switch is turned. Since there was absolutely no action or sound or any attempt to engage the starter I figured the selonoid needed to be replaced. So I ordered a new one.
I installed and tried - Same thing. Next, I load tested the batteries and found that the left battery (as you sit in the driver's seat) did not hold the load. I replaced that. Made sure both batteries were fully charged and tried.
There was 28 - 29 Volts at the selonoid but still absolutely not a click or any attempt to engage. One guy at the auto parts suggested it's going directly to ground but didn't elaborate.
I'm beginning to think I may have it wired incorrectly at the relay although I was careful to replace that with the original configuration.
Is there anything anyone can suggest? I've been working on this alllll winter.
As for the relay wiring, there are 4 connections on the right and 3 on the left as you look down from the seat facing the rear window.
Here's my layout:
Left closest to seat: Negative Battery terminal from right battery (facing rear window)
Left Small middle terminal : Green
Left Fuse terminal : Lavender
Right closest to seat: To Positive left (facing rear window) battery terminal
Right combo connection: Orange
Right Small standalone terminal: Red
Right Fused Terminal: White
The relay clicks and, as I mentioned, there is 24V at the selonoid. I measure accross the two large selonoid connectors and get 24V (28 Actual) when key is turned. I also get 24V from small terminal on selonoid and ground when key is turned.
Anything you can suggest would be GREATLY appreciated.

Today's Featured Article - The Rescue of a Fordson F - by Anthony West. Introduction I live in the UK and have for many years restored Fordson tractors (in the main model N's). I have also restored and shown model F's, E 27N's, Field Marshall Series 2, David Brown Cropmasters and the old rey Fergeson T 20. At one time I had seven restored examples which were shown and used in ploughing matches.
