Speed Merchant Posted July 8, 2020 Report Share Posted July 8, 2020 Hi We are completing a JPI 930 installation in my 1984 201 s/n 1442. I can't find the shunt for the stock alternator. Can someone tell we where the stock one is mounted? Thanks Curt Quote Link to comment Share on other sites More sharing options...
carusoam Posted July 9, 2020 Report Share Posted July 9, 2020 Hey Curt, I would expect on the firewall... with two large wires going to and from it.... and a pair of ammeter wires as well... Let’s ask @M20Doc (location of the shunt for an 84J) Best regards, -a- Quote Link to comment Share on other sites More sharing options...

carusoam Posted July 9, 2020 Report Share Posted July 9, 2020 The blue box is an auto message sender... (message sent already) ... and with Kortopates and PT20J ringing in... you have gotten some pretty solid answers... -a- Quote Link to comment Share on other sites More sharing options...
kortopates Posted July 9, 2020 Report Share Posted July 9, 2020 Thanks- do you know what it is mounted to? As Skip stated above, it's mounted behind the far right quarter panel with all the CB. The whole thing pulls out about 4-5", not a lot but enough. Besides being secured from the front it's also secured with hardware from below and the outside fuselage - don't really recommend tackling this till you look at the documentation in the service manual that provides all the details of what you need to know.Sent from my iPhone using Tapatalk 2 Quote Link to comment Share on other sites More sharing options...
N201MKTurbo Posted July 9, 2020 Report Share Posted July 9, 2020 It is really easy to get to if you pull the right radio rack. Sometimes easier than it sounds. Quote Link to comment Share on other sites More sharing options...

As others have said, many electrical items are between the firewall and instrument panel, above the copilots knees. Access can be a challenge, removing the seat, or the circuit breaker panel helps.

I was assuming that it was already removed as part of his JPI installation, but if not, yes removing it would help. Clarence Quote Link to comment Share on other sites More sharing options...
