Last week consisted of mostly R&R and service work at Maritime. At school, Travis demonstrated how a cam shaft sensor works. We hooked up the Motis scanner to the sensor and examined the voltage patterns the sensor outputs and talked about how those readings come about via a reluctor ring rotating in front of the sensor.

Small block Chevy had a dead hole. After a coworker pulled the head, he noticed the head gasket had actually been pulled into the combustion chamber slightly.

Last week I was tasked on a DPH drive service. The drive turned out to have water in the oil and bellows. I learned how to pressure and vacuum test the drive and make the necessary repairs. I also had the opportunity to drive a boat with Volvo's new IPS system on it, familiarizing myself with the all in one joystick control. It is an impressive system and the experience will help me in future situations guaranteed. More basic info on the IPS system here and here:

Last week we started class again studying electronics. We diagnosed a handful of test boards for voltage drops, opens, and shorts. I really began to understand diagnosing for shorts and how I can use an amp clamp to find them. At work, I mounted a nifty outboard bracket for a customer along with a skag pad on the deck.
