Last day

So yesterday was the last day of freedom before returning to work.  I had a pretty diverse day.  My ideas of mowing the grass were washed away by yet another very wet afternoon.  I attached the new stickers we picked up on the trip to the back of the party van.  The back window and bumper are getting filled with lots of adhesive proof of the various adventures the van has taken me to.

I also did a little digging into the additional noise I was hearing out of the van the last few days of the trip.  I turned it on and laid on the driveway to listen/look.  I saw the joint in the exhaust pipe in front of the muffler had only one of the original three bolts in place and I could see the joint was loose, leaking condensation and exhaust.  That would explain the extra noise I was hearing.  I should be able to fix it up myself this weekend with a new gasket and a few bolts.

Later in the morning I stopped by my mom’s place to give her a few souvenirs we picked up on the trip.  She was at the community pool with her “pool lady” friends, both of whom are two decades older than she is.  Mom liked the stuff although the small ceramic mask we picked up for her in New Orleans had a small piece crack off of it that I took home and glued.  I hung with mom at the pool for awhile talking about the trip and other things, it was nice.

Tuesday afternoon I did various things at the house like more computer work, planting the Joshua tree seeds I bought out west and getting a workout in although it was a big failure.

Last night was a running club board meeting but I skipped it.  The weather was shitty, the meeting agenda wasn’t pressing and I didn’t really feel like driving all the way into town for it.  Instead I used the time to do some spur of the moment work on the SSR.

Ever since I installed the Pioneer radio in my SSR I have had an annoying problem, I would get an engine whine coming through the speakers that corresponded with the RPM’s.  I have tried to address this problem a couple times, once by turning down the gain on the potentiometer on  one of the 3rd party modules in the install and a second time by relocating the ground to a different location.

Recently I was contacted by someone on the SSR fanatics site asking about my stereo install since he was installing a Pioneer radio in his truck as well.  During the conversation he mentioned how he simply used the ground built into the radio harness and did not run a separate ground wire to bare metal.  He said he has no electrical feedback in his install.  This got me thinking…

Prior to doing my install I looked into how others have done it.  The guideline I followed included a physical ground so that is what I did in my install.  However from my Tacoma radio swap I did no additional grounding and just used the factory wire harness and it’s built in ground.  So to test this theory I ripped into the dash of my truck for the 6th or 7th time.

I am disgusted at the rats nest of wires every time I pull the radio out.  Despite multiple efforts, I never found a way to clean it up that actually fit in the space I have available.  It took me awhile to dig through the cluster of wires to find what I was looking for.  When I looked at the ground connector I realized there were two black wires.  One of the wires was bare and meant to be used to ground other parts of the system, the other was wired into the factory ground in the harness.  Well I realized I had basically double grounded the system which surely was the source of my problem.  To verify this I removed the auxiliary ground and powered up the radio.  It worked fine. Doh.

Realizing this stupid mistake was aggravating but a relief at the same time.  After a difficult struggle getting the radio and it’s tangle of wires back into the dash I turned the truck on and revved the motor, verifying my noise gremlin was gone.  It was.

Putting the front dash panel back on was a pain in the ass but I already knew it would be, just as it was every other time I have had it apart.  Once it was all buttoned back up I did one more test run and again all I heard was music, finally.  Persistence pays off.

Last night I stayed up way too late getting caught up with Breaking Bad, watching the last two episodes.  Wow, some crazy, crazy stuff went down.  I had a hard time falling asleep afterwards even though I was exhausted.
