- Changed the oil
- Changed the fuel filter - need to order a filter housing seal kit or filter housing - during hand-priming after the filter change I saw air bubbles coming out of the heater electrical connector on the top of the housing
- Working on changing all four brake calipers and pads. The passenger rear inner pad was shot, rest all looked ok which makes me think I have at least a couple sticky calipers.
- Recurring P0380 every 3rd or 4th drive cycle or so. Glow plug fault. Pulled off the glow plug "controller", which is just two 70 amp ice cube relays. both relays bench tested bad. Ordered two new Bosch relays to replace.
- Hoping to get to PB Blaster the whole undercarriage if time permits tonight.
all of this is kind of a scramble in between work meetings, robotic build nights, and scout meetings. 3/13 and 3/27 Robotics tournament weekends with a scout camping trip Fri-Sun in-between and I'm the trailer-tow'r for both.
