Got it fixed !!!

Turned out that one of the two batteries developed a short in one of the cells and it was killing all the amperage it needed to spin.

Replaced the bad battery with a known good used one and ...voila...it cranked!

This after rechecking all my connections....

I should have remembered step #1 when troubleshooting any and all electric circuits, confirm that the power supply is good before proceeding to step #2.

When it comes time to get new batteries check around for a Rural King. They have decent batteries for $75-$80 each.
I've been using them for years now.

Glad you got it running!!

Yeah, I'm definitely gonna put in 2 new batteries, for sure!

But now I have another issue...

Man the gremlins are out to get me today!

When I put it into drive or reverse, check trans light comes on and bus does not go into gear.
Can't even pull codes on the dash pad, does not recognize my pushing down on the 2 arrow buttons twice for codes.

I bet I got another bad wire in that same connector.

Back under the bus I go!


Well at least it starts now, this should be somewhat easy now.
Hope my ECM didn't get damaged....

We shall see.

Woohoo...got it to go into drive !!!

I called transmissioninstruments, the folks who published the tech tips I posted. The guy there named Vojta (pronounced voita) told me when the WTEC 3 fails, it fails completely!

He told me my problem was most likely with the serial communications to the ECU.

The simplest thing to do was unseat the two round gray connectors that I had previously disconnected, under the dash and next to transmission where I fixed the bad wire, visibly check the pins were not bent or broken.

If that was good then the next step was to check continuity on the serial communication wires from the push pad to the Black connector on the ECU.

Well I got lucky, I after doing the visible check on the pins and reseating the connectors, I started bus and got it into gear, bus now moves!

Gremlins, get outta my way!!!
