(Battery Solenoid) - Applicable to all homebuilts. Continuous duty. 12V and 24V.
NOT FOR CERTIFIED AIRCRAFT
Showed up with the nuts and washers needed to make the connections and it works perfectly. The insulated portion for mounting allowed for 1/4 carriage bolts to be used. Came in handy getting it mounted, only needing a single wrench to tighten it down. Battery side clearly marked.
My master relay malfunctioned at an airport 70 miles from my home base. I couldnt start my engine, consequently I had to leave the plane their for the weekend. I ordered this replacement and it was promptly delivered in a couple of days. Once installed my engine fired up and I was able to fly home. Thanks Aircraft Spruce!
In 60F ambient, after about 20 minutes, the unit measures 140F. It was drawing .8 amps at 13.8 VDC.
Regarding p/n 11-03161, be aware that with the master relay in the battery positive lead circuit, as is commonly done, to actuate the relay coil you must provide a negative/ground connection to the coil terminal (not a positive) from your master switch or key switch. If this is inconvenient, a small control relay can be used to actuate the master relay, activated by the master/key switch.
First one sent failed the first time we booked it up. Intermittent. We had to tap on it to get it to work. Still waiting on a credit. Ordered 2 more, because they are specified in the stc we are using and I now dont trust it.
Per the manufacturer, the answer is no. The terminal going to the coil is the negative side and should go to the master switch, and the positive side of the coil is common to the power terminal.
Regarding part number 11-03161, the maximum inrush rating is 150 amps and the continuous duty rating is 80 amps.
Per the manufacturer, no it does not. Regarding part numbers 11-03161 / 11-05799.
We have added the drawing to the "Documents" tab of this web page. Please review it there.
The 70-111226-5B1 is a 12V continuous duty solenoid, so therefore the coil is rated at approximately 9 watts. Since P= IV. Or, 9=I (12). So for a 12 volt system, the current is 0.75 amps
No, because the starter circuit requires high amperage we do not recommend using this relay.
No, these master relays are intended for use on experimental aircraft only.
The single terminal version is the 12 volt. If you click for the full size image, you will see each image is watermarked with the sku for that product.
"Recommended mounting with cap down" per TDS.
