I've got a Centurion that has served me well for years but has recently
started NOT starting, in that the filaments are turned on, but the step
start that applies voltage to the primary of the HV (when in OPERATE
mode) is not operating
I've re=seated the cable connections to the interlock from the QSK
board (which sources the 12V to the step start) to no effect. The
interlock switch itself In series with the 12 V) measures 70 ohms which
is not going to help.
This problem started with turnon being intermittent after 6 mos of non
use. Now it won't start
Is there any way to clean these little microswitch contacts ?
