Greetings Hive Mind -- I'd like your help to identify the source of a sound and determine if its going to cost me $$$ or worse...
The hardware/configuration:
200 hour TTAE RV-7 with Lycoming YIO-360-A1B6,
Dual Lightspeed Plasma III ignitions,
Skytech PM/LS 149 starter,
EarthX ETX680 battery,
Cole Hersee/Littelfuse 24115 Master Relay,
Cole Hersee/Littelfuse 24021 Starter Relay - wiring as per OP-30, OP-31
Starter "jumper" removed - Starter Solenoid powered via separate 18ga wire from "I" post on Starter Relay.
The scenario:
OAT was about 40°F and I followed the normal pre-ignition sequence. I turned key to engage starter and heard a sound similar to a cat being crushed by the garage door -- a high pitched "squeeeeeeeeeee" followed by the engine firing on the first blade (< 180° of rotation).
The sound stopped the instant I released the key, so I suspect the noise is coming from the starter motor, starter solenoid, or perhaps the starter relay.
All the connections are tight, corrosion free, etc.
I did replace the starter solenoid at ~40 hours with the Borg Warner BWD S5613 and it's been trouble free since...
Anyone else experience this?
