I have no problem designing mounts and 3D printing it, the issue is that the Arctic 3.1 is about as wide as the stock light and it has the mounting at the bottom, meaning you need to translate the side mounts to the bottom one and there's not a lot of room to work with.

I'm not sure if they would be feasable to print (unless you have a metal printer, in which case - awesome!), but considering that I'd like to keep using the exiting mounting-posts... I've been thinking along the lines of fabricating a pair of "Reducer Brackets" (i.e. - bent steel, or milled aluminum) to step-down the mount...still just rough thoughts at this point...(applies to side-mount, but same concept can be applied and modified to allow for bottom-mounted lights) Edited July 21, 2023 by Cyberwolf Quote Link to comment Share on other sites More sharing options...

Critzlez Posted July 21, 2023 Share Posted July 21, 2023 Just wanted to have a ride update after 670 miles of riding. I switched to street tires after mile ~140, and the difference is huge for street riding. Other than that, no issues at all!! Motor bolts were all torqued to spec and had loctite (i got it from ewheels so maybe they do it themselves?). Only issue I have is the rubber flap not closing and the water resistance issues I noted and added a fix here 2 Quote Link to comment Share on other sites More sharing options...
Popular Post Al Alcatraz Posted July 22, 2023 Popular Post Share Posted July 22, 2023 (edited) 15 hours ago, Cyberwolf said: @Al Alcatraz - Where were you able to find power specs for the stock light and power/driver (18W) which was mentioned previously? I was looking for that info, but couldn't find it... I haven't had any free time to work on this yet, but as I couldn't find documented power specs, I'm planning to: 1. Temporarily route an intermediary cable betwen jacks on light and wheel, allowing me to a) - easily grab line-voltage with multimeter, and b) - use a Hall sensor to measure 'actual' draw (amperage) from the light. This should give me real-world power metrics. 2. Find the best light I can which falls below the previously identified top-draw, and go from there. If needed, I may try something more powerful but with a current-limiting circuit inline, but haven't got there yet - just know that I need ALL the lumens! I got that info from fellow riders who already dealt on the ShermanS with LeaperKim's ill-conceived headlight. Judging a headlight only by the specs can be misleading. For example, comparing the Arctic v3.1 side by side with the standard lamp, the contrast in favor of the Arctic is so stark you would never guess that there is only a difference in 2 watts. Also, I’ve found myself using the daytime running light most of the time. I am a bit surprised how much more attention I get in traffic (pedestrians are looking intriguingly on it🤩) because at first I was keen to have it just for the cool look.

I think a strip placed across the front bumper per Al Alcatraz’s post is possibly the best and easiest to execute solution, the Arctic light is appx 94mm wide at its widest point on the outer edges, tapering back to 92,75mm, though the gap between the bumper inner sides on mine appears to measure 93mm, so it may or may not squeeze in, according to how you may decide to fix it. I haven’t gotten round to removing the original light yet to check fully. The bracket for adjustment is on the bottom of the Arctic light, as shown, whereas the original light is held in place by bolts and nuts passing into the sidewalls of the light housing. No issues to fit into the original Sherman as there is plenty of space in between the bumper bars. Edited July 22, 2023 by Freeforester Additional info.

Not if you turn upside down the 3 lenses within the Arctic. Then everything equals out. 2 Quote Link to comment Share on other sites More sharing options...

Popular Post Al Alcatraz Posted July 22, 2023 Popular Post Share Posted July 22, 2023 He drilled holes in the cooling fins of the case. However his version of the Arctic has the cooling fins conveniently aligned vertically. Mine has them going diagonally. 8 Quote Link to comment Share on other sites More sharing options...
Hismajestycxplod Posted July 24, 2023 Share Posted July 24, 2023 What is your voltage after a full charge? My display sasys 126.6v. This seems too high. Also noticed the charger cycling on and off at the very end. The voltage going up to 126.8 turning off, dropping below 126.6 which turns the charger on again. Video of the phenomenon. Anyone seen this? Could this be a faulty charger? 1 Quote Link to comment Share on other sites More sharing options...

Anyone seen this? Could this be a faulty charger? I would not be overly concerned about what you are seeing. The on and off is cell balancing. It will go solid green once balanced. It isn't uncommon for the display to be off. Best thing to do is use a multimeter to measure pack voltage. You can then adjust the display voltage. I think the adjustment range is something like +/- 1.5v. Quote Link to comment Share on other sites More sharing options...

dycus Posted July 25, 2023 Share Posted July 25, 2023 Be aware that reading 127.5V vs 126V is only 1.2% off. Unless you're certain your multimeter is higher accuracy than this (i.e. has a calibration certificate stating so), you're essentially betting your multimeter is better than what they calibrate the chargers with at the factory. If it's not, you could be adjusting the charger to a lower (or higher, in some cases) voltage than the nominal 126V. Quote Link to comment Share on other sites More sharing options...
