Secret No. 10: You might really need that rewiring job he’s trying to pitch you.
Many do-it-yourselfers make matters worse for technicians, especially when it comes to wiring up various electronics. Standards, like those published by the American Boat and Yacht Council (ABYC), exist for a reason. Scrimp, or deviate from the guidelines, and you may be throwing roadblocks in the path of a tech trying to diagnose a problem. “Many times I’ve explained to a customer what we need to do is get this back to proper standards, because I can’t see the problem through the problems,” Hanks says. “It’s hard for us to accurately make a diagnosis if there’s so much stuff that doesn’t belong there.”
So what happened to my motor? Well, before my mechanic even thought about taking it apart, he checked the obvious while I stood watch. Sure enough, he found a loose “wake-up” wire at the electronic control module (ECM). He tightened it up and secured it for $40 and a couple of cold ones. He could have tried to sell me on a new ECM or some phantom ignition part. lucky for him, he didn’t.
