CHT, EGT no show...

[Jimzims]

Recently, on my classic sky view, both the CHT and EGT values display normally until engine start. As soon as I start the engine, these values all X out. This just stated to happen. I have had no problems with this display for the last 5 years.
Any thoughts as to cause or fix?
Thanks, Jim

Sounds like it may be an issue with either power or ground to the EMS. Be sure the EMS is properly grounded to the engine, as well.

Thanks, I will check that.

Still need help. The problem continues. The display will show normal egt and cht values after the battery re-charges following engine start. However, I have discovered that if I turn on the landing light and put that load on the battery, I then lose the egt and cht instantly, on the skyview. These systems are totally separate, so now I am stumped.
All wires and grounds look clean and solid. Any thoughts appreciated.
Thanks, Jim

Issue resolved, intermittent (poor) engine ground.
EMS functioning perfectly now.
Thanks, Jim
