Doesn't really answer your question, but I like putting the Watt Meter in the Topeak Wedge bag for a couple of reasons. First inductance problems are minimized since wire length only adds about 8". Second, I use the same Watt Meter (reversed of course) during charging. While I don't have the CA benefit of reading measurements during riding, I enjoy spot checking it during stops and at the completion of the ride. Not to hijack your thread, but even when the Watt Meter is not continuously available, the readout of max watts, amps, voltage are all useful regardless.
I've watched with great interest your build, especially for areas where the hills are significant.

Then you can adjust the TOP blue potentiometer to match the load. This will be a load of under 10 amps because most multi-meters cant do higher then that.

Thanks for your back channel help. I'm still a bit in the dark. My electrical knowledge is minimal.
I've got the Turnigy Watt Meter and want to mount it near the helm of my sailboat. This will require mounting the shunt remotely. I see the the photos of the removed shunt and reattached wires but I'm not clear on where the wires go. Where do I reconnect to the inside of the Watt Meter?

Mark F wrote:I have a Sevcon controller, can I connect directly to the +/- contacts (B+ and B-) on the Sevcon? Basically short wires attached to the Sevcon B+ and B- with a connector and plug the shunt in there?
