HVPS
Engine/LVPS Board
Measure the voltage at CN2-3 of the 
HVPS. It measures +24 V dc. If 
voltage is present at CN2-3, check 
for continuity between CN2-1 and 
CN1-2. If continuity does not exist, 
replace the HVPS. If continuity does 
exist, check the HVPS to engine/
LVPS board cable for continuity. 
Replace if defective. If voltage is not 
present at CN2-3, check the voltage 
at CN1-1. It measures +24 V dc. If it 
does, replace the HVPS. If it does 
not, check the voltage at CN2-2 of 
the engine/LVPS board. It measures 
+24 V dc. If it does, replace the 
HVPS to engine/LVPS board cable.
