What are people using. I can't find them in Assco or any of the usual places. Is there another name that they hide under. Thanks.....Geoff

Aircraft Spruce will almost always have what you want. My  starter does not 

pass through a battery cutoff relay so the max load I can ever see through 

it is 16 amps. I simply went down to the local auto supply and bought a 35 

amp continuous duty relay for $6 and used that. I figured that with the 2.5 

amp real load I will experience flying daylight VFR it's more tha adequate. 

If you really want the full meal deal head on down to your local RV dealer.

Geoff,



I got mine at B&C Specialty Products.

I got mine through B&C Specialty.  It came complete with all the diodes, 

as recommended in the Aeroelectric Connection book.  I actually got 

three contactors from them - the battery contactor, the alternator 

contactor (I'm using the Stratus engine), and the starter contactor.  

They're slightly different from each other, so you have to be careful 

which goes where.

I also installed clamping diodes on the starter solenoid and battery 

contactor on my plane.  One came with a diode and instructions, and I 

got a cheap diode (1N4003 I think) from Radio Shack for the other 

one.  The actual component choice isn't critical for this application 

so long as it is a solid state diode.



(On second thought, the first clamping diode may have been included 

with the magneto switch I ordered from Aircraft Spruce.  I think it 

was added by STC to keep the starter switch from failing.)



The clamping diodes are essential to keeping your electronics from 

seeing huge voltage spikes when the relay coil circuits are opened. 

Installation of this type of clamping diode is standard electronics 

industry practice any time a coil is switched in a DC 

circuit.  Without this component, a coil can generate thousands of 

volts in even a 5 or 12 volt DC circuit when the circuit is opened.

Thanks for the info guys

which one do I want. The link below will show 2 candidates.

http://bandc.biz/cgi-bin/ez-catalog/cat_display.cgi?11X358218



1 Continuous Duty Contactor 12 v  S701-1

2 Prewired Cross-feed Contactor    S701-2



Geoff....Do not archive



I know about as much as this guy.

At the moment the circuit was completed, I received a shock in the head and heard a crackling and boiling noise. This disagreeable sensation, which I feared might be dangerous, has deterred me so that I have not repeated this experiment."

S701-1 is the one you want. The terminal labeled "To Starter Contactor" 

also feeds your buss (or at least it does mine, which is a single 

battery system). If you have Express SCH, I can send you my wiring 

diagram off line.

Geoff,



I'm not sure we know enough about your application to answer.  I used the S701-1, which works in my schematic, but it might not work in yours.

This is a 701 by the way.

I'm going to have a simple system with an endurance bus, Capacitor, single battery, that’s about it.

I have a Rotax 80hp/Dynon D180/Garmin 296/Icom AC-A210/Dual controls.

Geoff

 Another possibility to consider as I assume your battery is firewall 

forward is a manualy operated Battery Cut Off Switch with an extension shaft 

I beleive they are available with an auxiliary contact to switch the 

generator as the continiously energised master switches solenoid operated 

type take about 1 Amp.

    I will be looking into this in the future as Ray has a 701 kit on order 

I beleive cat  MW002 available from www.deamon-tweekes.co.uk  in UK will 

suffice
