OneSaltyItalian Posted February 4 Report Posted February 4 (edited) ***UPDATE! 3/18/24*** The original issue down below has been resolved. Turns out my P-1000 just absolutely refused to accept the Tach2. After fighting with the airplane and working back and forth with the SureFly tech team, we got it solved. Between an oscilloscope and utilizing a multimeter to read off the Tach2, we figured it was the Horizon. I ordered an EI R1 on the spot. Installed the R1 and within an hour we were airworthy. That being said, here's some pointers for anyone who has this issue in the future and is coming to this forum like I have done with so many others. - Utilize a multimeter on the 0-5V output on the Tach2 to see if the Tach2 is outputting signal. The multimeter will get a spike, much like the oscilloscope, and tell you that the Tach2 is working. We found that the Tach2 was working and therefore that either our wiring was off between the Tach2 and the P-1000, or it was the P-1000 (it was). What we did for the longest time, until one of the bosses, Jason, at SureFly told us to, was only check that the Tach2 was getting power. We utilized the multimeter on the Tach2 power channels, not the output channels. Had we run this simple test (while the engine was running) weeks before, we would have confirmed it was the P-1000 causing issues. - Call SureFly with any issues. They're extremely helpful and always answer the phone during business hours. Their online troubleshooting guides leave something to be desired, but their willingness to help over the phone is awesome. PIREP!! Flying PIREP so far. Noticing lower fuel burn by about ~0.5 gal/hr. We just did a left side SureFly. Start up is BEAUTIFUL. I had a shower of sparks and we removed it. Now she cranks over in two or three turns. Nothing else like it! Please feel free to ask me any other questions! -------------------------- Hello! My A&P and I have been spending the past few weekends replacing our left magneto with a SureFly. From SureFly's recommendation due to the Horizon P-1000 we have, we purchased the Tach 2 as well as the Maggie Ignition Harness. We chose to go with fixed timing due to a C model with the carburetor as well as directly wired from the battery to the magneto. When we started up - it ran beautifully. However, the P-1000 was showing a "Left Magneto Signal Status Indicator. Turns on with the Loss of Signal from the Left Magneto. Flashes when the Left Internal Tachometer is Disabled." (we were flashing red) Has anyone run into this issue? We double verified that the Tach2 was getting power and verified the wiring was correct. Curious if we need to somehow reprogram the P-1000 due to the electronic magneto? We weren't able to see anyone with the same issue on MooneySpace from a preliminary search and we know plenty of folks out there have the P-1000 and SureFly. Thanks!

kortopates Posted February 4 Report Posted February 4 Unfamiliar with the P-1000. Does it use isolator resistors to connect to the P-leads? If so the fix should be to try different resistances. No reason to not leverage the advance with your C. It will only come with reduced MAP when you get up to altitude anyway.Sent from my iPhone using Tapatalk 2 Quote

There is a big warning on the surefly install manual not to install the mag with the Horizon tach or any other electric tach getting an input from the electric mag. The people at surefly are pretty nice to work with. People at Lycoming, won’t even return calls. (3 tech reps) -Matt Quote

(3 tech reps) -MattYeah, with the Tach2 it's okay, it's something they released in the past few years to make it work. I think that's what we're going to do - call the SureFly tech support folks. They're super awesome to talk toSent from my Pixel 5 using Tapatalk Quote

The EI R-1 uses a 5V square wave and requires a change of their insulator for the mag it is on from a normal P lead insulator to a VI-2UF. A JPI installation with a Hall effect sensor can be move to the right mechanical mag if you don’t want to buy the Tach 2.Sent from my iPad using Tapatalk Pro 4 Quote

Marauder Posted May 10 Report Posted May 10 Welcome back, we missed your experience and sanity. Good to see the B-26 back up there! How’s your F flying?I guess you can consider this a fly by (as opposed to a drive by)… Only jumped on the site to see if someone has a Spatial Interior installed so I can figure out how Bruce’s fuel selector/sump replacement piece is installed. Not obvious to me. That’s when I came across this thread on the SureFly. Just went through the installation, hence the carnal knowledge on electronic tach requirements. Hope you guys are doing well.Sent from my iPad using Tapatalk Pro 4 Quote
