bradp Posted May 29, 2012 Report Share Posted May 29, 2012 Hi All, I want to run my cylinder #3 CHT probe from a JPI 730 as a bayonet instread of a spark plug washer gasket. I understand the best way to do this in order to keep the original indicator operational is to piggyback the JPI and original bayonet using the JPI 5050-A adapter. I called over to JPI today, who said that they stopped making that probe. Does anyone have an extra 5050A that they are willing to sell or know where to get a hold of them. The other option would be to use the boss with a JPI bayonet and use a gasket with the original red line pane guage. The issue is that the original guage uses a single wire resistor type temp probe and that this would in all likelihood require a 337 to keep it legal. Thanks and take care, Brad Quote Link to comment Share on other sites More sharing options...
jetdriven Posted May 29, 2012 Report Share Posted May 29, 2012 Brad, we used a Type K 3/8" washer thermocouple under the factory probe. It reads about 50 low of actual CHT, but feeds the monitor and keeps the factory CHT. Instead of a threaded thing like the 5050A, its a washer unde the factory probe. I have an extra. PM me.

Cris Posted May 29, 2012 Report Share Posted May 29, 2012 Brad I believe I have a new one. Just checked and it is new although I did take it out of the package to inspect it. Sent you a PM. Cris Quote Link to comment Share on other sites More sharing options...
