Master & Starter Relays by Lamar - Grumman Style: Here we look at the Lamar X61-0028 (Master) and the X61-0030 (Starter) relays that are available. Video 1,324 in the Hit Parade.
I just experienced the starter contactor welding closed on a 172 I'm working on. I appreciate the in depth breakdown... my first time experiencing this. Awesome video!
Good job explaining the difference between the three and four post relays. Good job distinguishing the continuous vs intermittent duty electrical application. Any pilot procedure for a shorted starter relay during engine start?

Just replace it, glad the video helped.
Thanks for sharing the knowledge. The Lamar relays appear taller than the originals. Any fitment issues?
No, one is usually upside down so the master out is the same side as starter relay in on the same side.
@@GrummanPilots I see. So you are able to reuse the jumper p/n 902030-1?
@@macmak Sometimes, depends on size of unit (which has changed) and easy to make another jumper (I use copper).
