Is 1/2" gap all it can do?

Yes. It is a marine use one. Identical to the Mercury marine tester for 1/2 the price.

Road trip today. Them trees is quebec

It takes more energy than a half inch gap to fire an iridium plug under compression. That seem to be set up for a distributor type ignition system. Or about a 12-15 kV tester. Ill show you what I use tomorrow when I get to work

I just cross referenced the service manual. Got some more reading to do, but I am lake bound tomorrow in the Lund. I am beginning to wonder if the alternator is putting out something funky at higher rpms maybe. I have a prop with some chunks taken out that I am thinking about cutting down for a test prop so I can run the motor in the pond and get the rpms up without taking off trailer. Idler pully will hopefully show up tomorrow so I can do some tinkering in the PM. Optimax engines are voltage picky and slightly discharged battery can make them go nuts at times. Wondering if I can unhook the alternator and run off battery alone to isolate it.

My weekend


My son helping my at the shop this summer. Moving a large forklift carriage into the shop to be straightened with a borrowed Lull telehandler...I want one!


I was gonna stay home and relax and work on saws but went to recover this young couple on my favorite mountain instead.

Burning a field...so much for emissions in CA. Near the salton sea. It's common in this area.


Pinyon fire from a while back, right below Santa Rosa where I go...had me scared. Wouldn't be anywhere else to escape the summer heat if it burned.

 

[davidwyby]

Field fire from 8,000' and 30* cooler.


Porch view from the cabin I help take care of.

Golden hour

I am unfamiliar with these, but most alternator systems are connected to a battery already, so a voltage peek would be the only concern, as long as the batteries are fully changed. Most systems don’t mind some extra voltage, until it’s enough to fry something. Have you done a running voltage test? If the alternator isn’t charging, but your batteries are fully charged it should run fine until the voltage in the batteries drop

Got a call yesterday morning to see about going on a road trip with BIL he traded his boat for an atv. 7 hours each way. Back home at 130 in the morning and now at work for 645. Was a short night lol.

System is charging fine according to computer, but I don't know about output at higher rpms. I have been reluctant to take laptop out on lake, but it looks like I need to do that or cut down that other prop to get the rpms t0 4000+. Hour drive minimum one way to get to lake so I don't get to check what I have worked on with it very easy.

Put your voltmeter on the battery looking at AC voltage. Should be well below 100 mV AC.

Here is an adjustable tester I use. Numbers are approx. kV. You want it I'll send it your way. I got like four of these things!

Added some descr to my pics...easier on the desktop.

Thanks for the shipping offer but it looks like I can get one for $10 at the local autozone. Not worth spending the $ on shipping.

what did you use to get them unstuck?

A tug with my 4runner and my kinetic (stretchy) strap from ASR Offroad.

Those nylon straps are the bomb!![emoji6]

Nice dayPerfect evening
Had a major gremlin 250r that I am finally getting the bugs worked out

No constant AC voltage with fully charged battery when doing a ripple test. I'll do some reading on my meter to make sure DC is isolated. Diodes shot maybe? 90hp optimax being parted out down the road a little ways from me. May need a road trip.

If you have no excessive AC ripple then the diodes are ok.

Voltage jumps all over when checking. I'll have dad bring out his meter to check but I believe I saw some higher voltage. Meter refresh rate may have something to do with it.
