New regulator Worked?   The tach is driven by one of the three white wires..(three Phase)  coming from the stator to the  rectifier .  so if that particular wire is broken, or heaven forbid a winding in the stator is bad...then that would show no rpms..certainly... some three phase regulators should charge  with just two phases since all three wires go to three separate diodes first of all..and you get a high dc which is regulated to 13 to 14 volts.. With the engine running..an Ac volt meter connected to ground and each wire should show  40 to 50 volts ac...or an ac reading across any two of the three..measure all 6 possibilities...



  Doesn't sound like the Voltage reg??   The EIs box should show battery voltage on a certain screen...Herb

My new regulator came today for the HKS. 

You may remember the difficulties that I have had with RPM's showing on my EIS and my low battery alarm on my last video. The RPM stuff happened late last fall, when I wasn't flying all that much due to the weather. I just assumed that it was quirky by nature and bought a Tiny tach so that I would have some idea of what I was doing. I kept a battery tender on the battery all last year through the cold part and never flew all that long of a time when I did fly. So since my alarm was set at 10 Volts, I never saw any indication other than my RPM's that I had a problem, since I wasn't flying long enough duration to run the battery down to the alarm setting.


I had talked a bit with Grand Rapids Tech about the RPM issue, and was told that the r/rect. on the HKS did not charge if the battery was up to full charge. Having that in mind I took the battery tender off this spring when the cold weather quit, hoping that the RPM;s would show up again if the battery wasn't topped off. Nope!


So the long flights looking for my errant bird finally ran the battery down to alarm stage. Now I will confess, I do not see myself as a mechanic. In fact if I happen to get grease on my hands, I consider the whole day to be a loss. So me not tumbling to the fact that I had a problem was not a surprise.


I managed to get the new one in place.

My information indicated that if the r/r wasn't charging, there would be no RPM's shown. What I was advised to do to get them shown was to put more of a load on the R/R to cause the charging circuit to kick in.

It is also my understanding that the things either work or nothing works. There is not supposed to be any middle ground. This one didn't work.
One thing I do know is that the other one was not producing any charge, this one is. If the wind dies tonight, I will fly it a bit to see if the RPM's continue to register. If not then I will fly in the morning.

  Interesting ...a lack of ac pulses to the tach circuit in the Eis box..would only be dependent on amplitude...and possibly the diode that sees that white wire in the Reg. could have been shorted which would kill the tach pulses...not an uncommon failure mode... Herb
