Those were fun. We both three trucks from one company. Inside all three the series parallel wires were fried that would charge the other batteries when the parallel switch was not in use. I found out The previous owners mechanic had a big welder. If the truck wouldn't start he'd hook the welder to the positive terminal and stick a big welding rod to the frame.
As long as you could find it! CAT hid some of those pretty well, especially on the scrapers as I recall!
That's why they publish the most unread book in history, "Operators Manual"! At least back in the day before how to tune the radio became more important than how to check fluid levels!
Yeah well, the outfits I worked for had machines made before they cabled the OM to the seat, and most of our "operators" had never seen one before their first day, lol
Well you would have to look a long time seeing as how over 90% don't have them or even have batteries .
You wouldn't be needing to start them then, would you?
The few scrapers that have engines if they have batteries the switch is on the control panel , those that don't the switch is on the tractor.
The 613 scraper don't have a engine. The tractor disconnect is where it is on most tractors. You lean over the seat and it's right there next to the shifter.
