Ah, the frustration! Most of us have been = there=20 (some more than once)

You mention two things - you installed the new = regulator=20 AND the instrument panel shifted from its original position just before = the=20 second start. I strongly suspect that one of those actions may = well have=20 contributed to your EM going bananas and perhaps other problems. I = would=20 check my grounds for certain. If you do not have a good electrical = ground=20 then there is no voltage reference for the chips and they can = do all=20 sort of strange things.

I would think the easiest (could be wrong) thing = to do is=20 to disconnect the voltage regulator temporarily and see if that has any = effect,=20 next I would check to make certain I had a good electrical = ground.

Good luck

Subject: [FlyRotary] More = Musings...ah=20 screw it, just shoot me!

Got off work and happily headed to = the=20 hangar. I was able to get it to start and stay pretty cool for a = while=20 as I played with the settings. Switched from Controller A to B, = back to=20 A, disabled the Primary Injectors, the Secondary Injectors(in = succession=20 <g>), switched back to B, did the disable toggle = spring switch with=20 an expected drop in RPM...switch back to center and expected RPM = returns.=20 Throttled up and the RPM steadily increased without jumping around = until it=20 got to 4999 or so and went to zero and started jumping around above = 5000=20 rpm......no big deal yet as we discussed the possible noise issue = yesterday=20 and I have not checked the problems yet. Used my laser temp = gauge to see=20 if the engine and the EM were kinda close, they were. Tried out = my new=20 Harbor Freight laser RPM gauge, but couldn't get it to work = right. Ok,=20 Several minutes has gone by so I shut down to let it cool. Tried = to=20 restart to no avail...so I decide to let the system cool for an = extended=20 period.

While waiting I decide to install my = new B&C=20 $230.00ish Regulator. Already have one of these gems on the = primary=20 battery system and feel it is time to install the new one that arrived = a=20 couple of weeks ago on the Aux side of things, so I shut down all the = systems,=20 disconnect the batteries, crimp some new connectors on some of the = wires to=20 fit the new regulator get everything hooked back up and feel pretty = good about=20 the night. Heh heh heh, silly me.

A while has gone by and = everything seems to=20 have cooled off. I hold my tongue just right and crank the = engine and=20 with some grace of the engine Gawds the thing cranks up. = Wait...what is=20 this...the EM is showing the RPM, but, but oh, damn it is flashing = NOP. =20 It was not doing that before. Damn. Hmmmm, the Coolant temp and = Oil temp=20 are showing exactly the same temp at 44 degrees....lets see if they = start to=20 raise....Agggghhh, no, they are both stuck on 44 degrees F. =20 Geeeez. I know, lets try the "B" controller and see what=20 happens......NOOOOOOOOO, I switch to the "B" controller and the engine = starts=20 to die. Damn, damn, damn. What the hell just happened????? = Thoughts????????

Yes, I am disappointed in the evening = that=20 started on a positive note. This (Monday) is my Friday night and = I have=20 the next two days to make progress. If'n y'all have any easy = answers for=20 me I would love to hear 'em as I would like to think the next two days = would=20 be steps forward as opposed to just trying to get back to where I = was. I=20 did not even start to troubleshoot yet as I was too frustrated and = needed to=20 walk away for a while to sulk <g>. Did I fry the "B": = controller=20 with a new/better regulator. Everything was disconnected during = the=20 install and nothing else changed....OTHER than the instrument panel = shifted=20 from its temporary mount just before the second start.

Hopin' for some insight and = perspective before I=20 go kick my dog when I go to the hangar tomorrow (ok, I would never = kick=20 Winston he is really a good dog, but y'all get the idea). As always, = THANKS=20 for your support.
