Ivan Haecker" Subject: Re: AeroElectric-List: Local Automotive Source for Starter Contactor? Numerous Ford vehicles in the 60's through at least the 80's used a similar starter relay. The real problem is getting one that actually works for a decent period of time. I have a 1988 Ford Bronco II that recently needed a new contactor, so I went to my local NAPA to get one. It failed within 2 weeks, and worse yet, it failed by not disengaging! I returned it and asked if they perhaps had a better quality one. Paid a little extra, but same problem within a month. I finally put an old salvaged contactor from a derelict Cessna 150 on my Bronco and it's been fine every since. My take is that it might be difficult to get a quality unit from a chain auto parts store. A contactor that doesn't engage is one thing. It's a lot worse when it won't stop cranking your engine. I still drive around with a handy wrench to disconnect my battery. Fortunately, in your plane you can turn off the master switch.

I have a 2001 GlaStar that is about to get a glass panel upgrade. I bought a B&C BD410-H alternator to replace the vacuum pump. Since I believe that would easily be able to power the entire plane and I don't have an engine with electronic ignition I was leaning toward Z12 with no endurance bus. However I've also been studying Z13 to see if it makes more sense. I'm open to opinions on what to do in this relatively green-field application. --Rick On 8/15/2017 4:59 PM, don van santen wrote: > Listers, > > Roughly eight months ago I asked a question relating to the Z12 diagram. > I stated that I have Z13/8 system and was considering changing to the > Z12 to take advantage of the additional power that the SD20 alternator > offers. > > Bob responded that he would not recommend this as the Z13/8 offers more > levels of protection.

Thanks Ivan, I'm going to try a NAPA ST404 and see how it holds up. It is taking a little work to get it installed, with the terminals and mounting holes being different than the old one. I didn't see you at Oshkosh this year were you around? On August 16, 2017 11:19:14 "H.

Yes, I flew Mark's Patrol up there, but since it was damaged during a demo flight, I got to fly the LSA back to Texas. I was impressed with its performance. I believe a company named White Rogers makes a good quality stater contactor.
