Mechanic's Assistant: Sometimes things that you think will be really complicated end up being easy to fix. The Heavy Equipment Mechanic I'm going to connect you with knows all the tricks and shortcuts.

Mechanic's Assistant: Anything else you want the equipment mechanic to know before I connect you?

Can't scan the ecm. Says there's no presents of 12 or 24v at the OBD connector. No blown fuses found and the engine light is on. Using a snap-on solus
