More Good News-Bad News

Good news first: 

(1). The long-awaited temporary exhaust system is in place, and it feels like a huge step towards the first engine start. The job was surprisingly easy, and I actually survived crawling around on the concrete floor for a couple of hours without too many additional aches and pains. That said, it was a job that would have been much simpler if I had a hoist or a pit in my garage.




(2). I decided to take a chance that I won't need to have easy access thru the driver side floor panel and forged ahead with driver' side carpet and seat installation. That job also went quite well and I'm mostly pleased with the results. One semi-serious disappointment is that the seat will not fully recline as the release handle on the seat back hits the wide hardtop style rear armrest. I had relocated seat mounting brackets as close to the console as possible without major redesign, so I'll have to be satisfied with what I have, at least for now.


                                   Now the bad news...and this one could be serious. 

I've been checking all the driveline related systems to make them ready for the big day, and among them was a checkout of the start circuits and the function of the late model mini-starter. Previously, all I had tried was to hit the key and see if the starter relay was switching power to the starter. So far that simple test had not indicated a problem, but now I want to spin it long enough to pump oil into the engine, and after engaging the switch for a few seconds, I could tell the starter was turning much slower than it should have. In a few seconds, the 50amp circuit breaker on the power cable tripped.

 About 30 seconds later the breaker reset, so I turned the key again and the starter began to spin. The dash lights dimmed, and the voltmeter fell to zero, but I stopped before the breaker tripped again. So that is where it sits today, while I contemplate the possible reason, for the heavy draw.

According to the charts I consulted, the 2-gauge main power cable should easily serve the 10 ft from the trunk mounted battery to the starter with only the LED dash lights adding a miniscule draw to the total load.  So, for the time being I'll consider other possibilities.

The obvious first guess is a bad starter, which would be frustrating as it is supposed to be a new part, not remanufactured, but that would be the easiest fix. 

I don't even want to think that something in the engine might be binding. I rebuilt the engine in 2015, so it's not fresh in my mind, but I don't recall anything being a problem. I do remember checking the rod and main bearing clearance with plastigauge, as that's the way I've done it forever without any problems. Since it was assembled, I've turned it over by hand many times and I certainly should have noticed any binding. That said, I no longer trust my memory or my mechanical abilities. Getting old really sucks!

Yesterday, the city water pressure dropped to almost nothing when one of the wells broke down. We could have easily gotten by as I have emergency water storage, but the electric water heater shut off when the pressure dropped. I showered and shaved with cold water this morning as the pump had not yet been repaired. That means that household problems once again takes priority over playing with my car, so it sits for now.
