Upd 2x0 217 power board

• PCB Hardware Assembly PFCmdMenu iochan Merge
• PCA : SC/MC 218 FET 217 Swiffy

FET 2x0-217 PCA

200-217-001

• 3-28-09 : removed from AK-WB2 w/exploded power FET

todo

• remove damaged power fet
• test other power fets (safety fets are on and will complicate this.)
• if all other tests are positive, apply 10 volts with a 100mA current limit
• if successful, attach to state controller with "testjig" software build and apply 20V limited to 200mA
• if successful replace missing FET and repeat above power tests.

200-217-005

• 3-1-09 : Vclamp circuit failed (permanently on) when MPJA power supplied failed.

todo

• replace PFET and power resistor

200-217-006

• 4-2-09 : started bench test at 3:10 am

200-217-009

• 4-1-09 : removed from WB1 - possibly damaged
• 3-28-09 : measured battery voltage at zero and 1.8 volts
• 3-28-09 : measured terminal to terminal resistance of safety FETs, 38 and 72 ohms
• 3-1-09 : safety fets are not engaged.

todo

• replace coin cells (use adhesive to secure batteries to PCA)

200-217-010

• 4-2-09 : measured coin cells at 2.7++ each.
• 4-2-09 : bench test for 1.5 hrs with 218-010
