Default Takin' on the Anthony Wayne Bridge

I wanted to (& my buddy Sid suggested) get some amp readings
...while goin' up/climbing a hill.

I took El Moto down to/by the Maumee River
...to find some bridges.

The biggest bridge that we have here in Toledo is called the "High Level Bridge"
...or officially designated the Anthony Wayne Bridge

* I believe it's named after General "Mad" Anthony Wayne
...he was supposed to be a "trail blazer" of this area back in the "pioneer days"

From what I'm seeing, the Max Amp draw seemed to be in the 200A-300A range
…& the constant Amps seemed to be in the 50A-60A range

Is that what you'all see?

Here is a video of the ride/data

I've been lookin', seems like, forever for a "base" or box to mount this Amp meter into.

The top or opening, of the container, had to be able to hold the (4" x 4" x 2") "square" meter
…& the bottom had to be (~3 1/2") round, to mount on the bike

Well, lookin' around & thinkin' "outside of the box", I found a 1qt. Brake Fluid bottle that had a ~3 1/2" circular bottom
…& flexible enough to conform to a 4" x 4" square
(fits nice-n-snug)

So, I drilled some holes, in the bottom, for the wires & bolts
…& then, added some mounting "studs"

The wiring is super simple (doesn't even need a power supply)
...only has (2) signal/sensor terminals

It didn't come with directions or a wiring diagram so, I figured the (1) marked (-) must go to the battery pack negative (B-) side of the shunt (black wire)
…& the other (1) must go to "power draw" (P-) side of the shunt (yellow wire)

Outside of the fact that you should paint the can black, that fit is sick!

Default 250 e-mile update

Well, I've got over 250 miles on 'er since the conversion to electric
…& I'm happy to report that (knock on wood) everything seems to be goin' good.

The bike runs great, is very nimble & has great acceleration
...like 0 to top speed (35MPH) in ~4 seconds

I gave everything a good "lookin' over"
...went around double checkin' the bolts
…greased the idler sprocket bearings
...& the inspected the sprockets (they still aren't showing any wear)

Then, I took 'er for a ride to get some data with the analog Amp meter.
