Short version: flew - landed, sat 20 min, lack of starter engagement on restart. Click - -
Anyone else had this happen with the SkyTec LW starter?
Long Version background:
RV7 - SJ Cowl
YIO-360 M1B - stock - w/SkyTec LW starter
14 hours into PH I
Moderate OAT 45 F, flew 45 min made a good landing and decided take a water break. The plane sat with no wind for 30 min, then got to starting - just a click, 10 times ( maybe more, it was a lot) Click- clearly the start contactor on the firewall, but no other sounds. Finally, kept up the attempts and it engaged and spun and started. Until that, nothing but clicks. The voltage did not drop either.
The plan is to decowl and run some wires to test voltage:
1. to starter via large cable,
2. voltage to the start engage wire from the FW contractor.
In addition, place a thermocouple on the starter solenoid (for SkyTec techs)
Possible issues:
Bad FW Starter contactor - not passing voltage to starter
Hot starter solenoid - needing more voltage for pull in than available
I pull tested all the big terminals by hanging (me) from them. Book pull test is 525 lbs and granted I am only 150, but not loose. This only happens when it is hot, this is the second time for the click event.
