Exact replacement for our original relay which was installed upside down (see FAQ for proper orientation) and failed after 7 years/475 hours. We’ll see if this one lasts longer when installed correctly.

Any product eligibility information provided here is based on general application guides and we recommend always referring to your specific aircraft parts manual, the parts manufacturer or consulting with a qualified mechanic.
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.
This is shown cap down on our website, the writing is not upside down.
