Short in Pasco Power zone - No Ops session

About a week ago, an occasional gremlin short in Pasco power zone became a full blown gremlin!! I have spent several hours tracking it down and have eliminated most of the easy ones. Still not working. I canceled the June 30 op session...sigh...

I am pretty sure it lives in the common rail wiring. Next week I will begin to disconnect all the leads and rebuild the bus.

My plan will be to add another (3rd) Digitrax PM42 power zone circuit board and subdivide Pasco zone into 4 Zones thus further dividing power zones:

Reversing PM 42:

• Short detection for reversing sections
• Biggs OS to Troutdale OS
• Balloon Track in Portland
• Open

Second PM42 will have

• Portland Yard including Eugene
• Seattle Yard
• West Half of Main
• La Grande and Spokane Yard Staging

New PM42

• Pasco yard
• West Pasco and Walla Walla
• East half of Mainline around Pasco
• Aberdeen and Helix
  

then re-attach leads to separate bus wires. Hope that does it.
I have spare PM 42 and am ordering more TAP 3M connectors from Mouser.
Hope to start work this week.
