This is working for me on the Blades.

I bypassed my meters on all my Blades with a Molex and 330 ohm 1/2 Watt resisters.
I used a 12 Pin Molex Mini-fit Jr. I jumper'd the following.

1 to 7, 2 to 8, 3 to 9, 4 to 10, 5 to 11 and 6 to 12 with the 330 ohm 1/2 Watt resisters. I
No more meters or meter failures.

I'm not sure how to attached a picture but I have a picture of one. I've been running 3 of them since the first of the year. Works great in the Blades

Thanks for the info GK,

Did you use axial or radial type?

How did you determine the 330ohm amount?

gbknox:
I used axial resisters. I can't take full credit for this, the first Blade I purchased had one installed in it. I just replicated it.

Hertz14:
Thanks for the photo, looks simple enough.

I’m curious why 330ohm was the number that was landed on- all of my meters have a static resistance of 121ohms +\- 1 ohm.

I’m thinking about making one myself to try, but going with a lower resistance, say 130.

Have you noticed if the resistors get warm on yours? Thinking that the higher resistor would generate more heat.

Trisail:
I don't know the voltage the meters use on the BB's.

But to answer the question of 330 ohm to 130 ohm change- ohms law E=I*R.  Power (watts) = E*I

Assume 12VDC. 12=I*330, 12/330=I, .03636=I. About .037A
or 37mA. Watts = 12*.037= .444. 1/2 watt resistor is correct.

Assume 12VDC. 12=I*130, 12/130=I, .0923=I. About .092A
or 93mA. Watts = 12*.092 = 1.104. 1/2 watt resistor is not correct. 1 watt resistors would probably be ok but 2 watt would be recommended. Would be hotter. Not sure what the detection circuit is rated, I would not lower the value.

A larger value ohm resistor would reduce current and therefore less power (watts). Not sure what detection circuit lower limit is.

With 6 1/2 watt resistors at .444A the resistors would be the
equivalent of about a 3 watt light bulb.

I don't know the circuit or method of detection for the meter tilt - will assume current draw??? The resistors work at 330 ohm 1/2 watt - I would use that method.

This assumes the resistor drops all the voltage and uses all the current.
