I did my starting/charging system test today and now I have two more trucks to do it on at work... Gotta love intermittent start problems! Going into brakes now as I was working on a Utility Trailer at work I'm learning the joys of parts support for aftermarket TPS and central lube systems. The TPS is a PSI system manufactured by Meritor so I was able to find the hose that I needed but the grease setup is its own nightmare. I had to retrofit the trailer over to newer style auto-slacks and inboard s-cam bushings which required a couple of "interesting" adapter fittings (You would not believe how long it took to find a 45 degree 1/4 x 28 - 1/8" NPT).

FQ2013
Took the air brake pretest... Not good.
Moving on into brakes I have to do a brake job on a trailer with TPS. Should be interesting, what could go wrong right? I built a bearing washer that should speed up turn around time on my brake jobs quite a bit.
This week I've learned how to track down parasitic loads using a voltage drop across the fuse and I think I've come up with a way to track it even further using voltage drop testing. With a test lead on the ground post of the battery and the other test lead in hand, in theory one should be able to test all the way to the suspect component without an amp clamp. Since if there is no flow there is no current drop the reading will be 0.00 at the suspect component if it is not the culprit. However if there is a measureable voltage drop any point in the wiring harness (Test using back probe etc...) you can follow it all the way to the culprit.

Update
Failure on the cruise control problem... I thought I had it tracked down to the faulty park brake switch but after a jumper wire test fix still no cruise. The throttle set does work though so it's probably time to tear apart the dash and check the brake switch.

FQ2013
So I pulled the hubcap and found this... Looks like money to me!
Also in class I found the parasitic drain on the Peterbuilt and the International. Crimped a battery cable end as well as Deutsch and Weatherpack connector pins. My electrical is starting to come back to me now... I think I found why the cruise control doesn't work in one of our fleet trucks (We'll see tomorrow).

Neat...
Now I've been looped into presenting at our safety meetings... Neat deal. Learning all kinds of things about regulations...

And it just keeps going...
Got truck 280 back... $11,800 later it has a new engine. Now it's in the shop getting a water pump and I noticed a puddle of gear oil under the front driver this morning. Neat, because I really wanted tear a rear end down to change the front cover gasket.
Valley Freightliner is putting on a training class next month that I'll be going to, "Multiplex Electrical & Smart Switch Training". Should be good!

Summer 13
More interesting times... OSHA inspection last week. Coincidence? And then a literal pile of steaming feces awaited me in the loading yard on Saturday. I think someone may have been a little irked over being fired... Apparently the belt drive grinder with all the guards broken off is no bueno. Who would have thought? And maybe the pvc airlines, complete lack of chemical inventory or MSDS's on file, and the loading dock is well... We hired a structural engineer from Carlson Steel to draw up a few modifications to pass the OSHA inspection. Spent some time with him today and he thinks he'll have his report done by Monday. Because I didn't have enough to do already!
Learned that neither Motor Trucks or Valley can look up trailer brake parts off VIN or axle numbers... What if I want to have the parts sitting on a shelf before I tear the trailer apart?
