I just bought an SDK8 and found this thread while looking for info, and it was a great help! I needed the wiring diagram in the manual to get it running.
I haven't researched it enough yet to know what year mine is, but it has the 2J diesel engine in it.
It had sat for several years after the man that owned it had passed away. the last person to try and start it may have done something wrong and fried something because there was no response when you turned the key on. No voltage. I swapped batteries, no change. Checked all fuses, all ok. Followed the wires to see if mice had chewed them, all good. We ended up running a jumper wire from the battery to the ignition switch and spliced it with the "battery" wire from the harness to energize everything else on that circuit. Turned the key and the panel came to life! But still would not start. I unplugged the starter relay since it was not clicking when the key was turned and applied voltage from my jumper directly to the plug to engage the starter and it fired up!
Before adding the jumper, we tested for voltage along the harness and I had 12 volts at the ignition switch but only when the "battery" wire was disconnected. Connect it to the switch and voltage was 6. The switch works now with the jumper so I don't think the switch is bad. I'm going to open up the harness and work my way back and see what I find, maybe it's just a corroded connection somewhere. And get a new starter relay.
I did notice a bit of banging from the left front corner when it turns. Not really jerking or a vibration while it was banging, but it's only from the left corner, behind the wheel. It doesn't matter which directing you turn, or which lever you push or pull. Going forward or back it's fine in a straight line, but as soon as you turn, bang bang bang. Like a loud knock. Sounds like someone is hitting the metal with a sledge hammer. Would a bad axle bearing or chain sprocket cause that noise?
Does anyone know of a parts list for this machine? A break down of all the parts with part numbers?
Thanks for the help!
I'll post pictures at some point.
