Just had my first engine start today. WooHooo!!!
I did realize an electrical problem prior to the start where the solenoid & Master relay join. I placed a red jumper to bridge the circuit on the master relay. (See image link below) I had to remove it once started to enable my eis4000 and avionics to run. I'm running the exp2 bus which isolates the avionics bus in start mode.
The engine ran terrific, nice & smooth through all rpm ranges up to 1700.
That's as high as I went today
Ran it for .2 hr, here's the readings just prior to shutdown
Oil Temp=119
Oil Pressure=68
EGT 1177, 1191, 1146,1184
CHT 309, 342,342,358
Any advice on my electrical problem?
Should my diode be connected in the place of my jumper?
Would the diode there enable the starter to engage, then release to enable the closed circuit to power the avionics bus?
