Tracked my no crank issue down to bad grounds. Ran a car booster cable from the - post of the battery up to the where the ground cable terminates to the chassis near the engine. Turned the key and the starter leaped into action, although it was moaning and groaning about it a little. Had to persuade the starter to engage the flywheel with a screwdriver but it spun the engine right over. I spun the engine over on and off with the starter for a few minutes just to get it used to spinning again.
I'm going to pull that ground strap and clean it, as that seems to be where the ground was losing touch. should be good on wiring from there other than the lights and wiring in some new fuse holders, I am just using jumpers for testing purposes right now. Had to sort the wiring for the fuses out, each one had a wire unplugged.
Somewhere in there I put the PTO switch from the '76 in the '78. The contacts on the one from the '76 looked brand new and the action of the switch itself is perfect. The 78's had seen better days and the part of the switch you lift up to engage the PTO was rusted in place preventing you from turning the PTO switch on.
Next step is to see if we can make it produce some spark at the spark plug.
I'm going to have some dinner and see what else I can get done on it this evening.
