 Posted: Sat Apr 01, 2006 12:37 pm Post subject: Dual shunts and amp gauge |
 |
|
I have single battery/dual alt setup. I also have EI volt/amp gauge.
The amp gauge works using an external shunt but the value of the shunt must
be known in order for
the gauge to work properly. Therefore my gauge is VA-1A-60, works with
50mV/60amp shunt.
The shunt wires to the aux alternator lead is 50mv/10A and therefore may not
work properly. I
would like to replace this aux shunt with 50mV/60amp so that I can switch
from MAIN alterntor
to AUX alternator and read the current on the EI gauge.
Is there any harm in using 50mV/60amp shunt for the aux alt when
aeroelectric connection shows 50mv/10A?

No. If you have a 10A shunt from either me or B&C, I'll
swap it for a 60A.

I countersunk the mounting holes in my 60A shunt so its no longer 'as new'.
I'll buy another one from B&C. Thanks for the offer!
