T- 2.6.6 HEATER SWITCH OKAY / ISOLATE HEATER CONNECTIONS
Per the Figure below, measure BETWEEN K1 and K2. Between 9.0 and 15.0 Ω?
Yes Between 9.0 and 15.0 Ω! The Heater Connections are OKAY! See procedure number
T- 2.6.7 (page 298).
No More than 15.0 Ω! Check the heater wires for a ‘broken circuit’ between the Power Control
Board’s K1 and K2 and the distribution board’s Heater Connector.
T- 2.6.7 HEATER CONNECTIONS OKAY
a) Figure right, reattach all cables
PROPERLY to the Power Control board!
b) Remount the Power Control board to
its clips

but do not bolt it in yet!
