I'll get everything setup with the solar shunt first and then look for more info about modifying the analogger. JLE wanted to post that stuff up, but it looks like the Sun Tour may be a little more all-consuming than he foresaw. If he doesn't get the post up and your other solar tasks are complete,...

Hmm - okay. Justin is in France just now, but Robbie and the guys can address your issue. It does sound like it took a static hit and something went south. Maybe you could get Justin to stop by for a consult on his Sun Tour excursion...

So - no arrow flipping when you shorted the unsoldered pad? This seems like an odd out-of-the-blue failure. When did this occur? What firmware were you running? Yep - my first bike has a radically customized CA installation and I hate to touch it. The only plus side is that everything is connectoriz...

Tek, next question : what voltage would i expect on the SP pad? I'm measuring 0.6V against GND. Is that ok? And if not what could cause that? Oops. I just checked the schematic - I had forgotten about the Schottky diode there with the cathode on the the Sp pad. So - electrically dissimilar from the...

My question about the speed sensor was on the electric side: Can i test it? Do i test resistance of it? Or apply voltage? Is this a hall sensor? If i open the 2 pin connector between the CA and the sensor what can i measure on the CA side and what on the sensor side? This would help me narrow down ...

All Grin products are designed to plug into CA2/CA3/Grin Controllers/etc. You don't mention what you are connecting to.

Here's the pin out from the sale page - if you aren't connecting to a Grin device, make sure it matches.

Hey izeman! uite some month i decided to upgrade to latest firmware. read something about a 3.1 RELEASE version, but couldn't find any. is b22 the latest version? The latest release is 3.11b2 but a b3 is about to be released to fix up a display glitch discovered by Marc S. (thanks Marc!). So - what ...

Battery 48v nominal 54.6v full charge. Travel 9.5km and battery dropped to 49.9v ... Battery is quoted as a 20ah battery. (54.6V) / (4.2V/cell) = 13 cellGroups Assuming this is a resting voltage: (49.9V) / (13 cellGroups) = 3.84 V/cellGroup Using CA3 SOC tables for Li-ion cells, this is about 61% S...

I hear the charger come on for a few minutes a couple of times every hour. My plan is to leave it on until I go to work in three hours (total of 5 hours balancing), where I can top it off and keep it charging/balancing for a good 6 more hours. Ride home and do it again. This seems to be behaving as...

I would unplug as soon i noticed green light. I assumed it was done as i use a luna charger. I'm not sure what that means - in the end the Luna charger is just another CVCC charger. Also, disregard the illustrations they have about charge cycle voltages - charging doesn't really work that way if yo...

I went about the business of breaking in and balancing the battery with 5 relatively shallow charger s to 58.8v (measured with multimeter and charger) and allowing the balancing to do its thing until I saw the green light . Feeling confident that my battery wasn't spending too much time in the bala...

Correct me if I'm wrong, but if I 1) update a CA 3.1 with this aforementioned special sauce firmware, 2) purchase and install the Grin solar shunt, 3) mod my Analogger to feed the CA, then my solar e-bike should be state of the art? Yep. The firmware that JLE linked in above is really an in-house d...

Battery voltage in the main screen and 'Electrical Stats' is correct (anywhere else its correct as well). Only if I switch between battery's with the two main buttons, the 'Battery choice pop-up screen' ..." Ratz - missed that one. Ok, I have PMed you an alpha test version that should correct the d...

From A 'Sun Trip 2018' trike:

I think I found some bugs in FW v3.11b2 ;) Hey Marc! This is good stuff (not that I'm happy to see bugs, but...) battery: -if I switch between battery A and B, the voltages are shown as 0V (Ah value are correct, battery set-up is correct, ect) I can't seem to duplicate the battery issue. -How are y...

... I'm going to set one of the momentary switches (ignition, I think) to simply short the aux signal to ground and set the CA AuxD Control Type to 1 button mode. Exactly. This gimmick was called out in a DigiAux document that was pulled from distribution when we switched to Schottky diodes - we ne...

What does the new bypass, WOT, etc throttle modes do?

Both the Setup Utility Help File and Tool Tips explain these modes.

This was considered, but it didn't seem an option many would find attractive so the Presets option for DigiAux didn't make the cut. (EDIT: NO!) Oops - been away from that code for too long and 'misremembered' the final outcome. The statement above is incorrect - Presets are supported by the DigiAux...

Would the controller have to be powered on for the CA to measure/record the solar charging current? No, the controller doesn't need to be powered on, but the CA does so you may need to mod the CA-DP connection if you are powering the CA from the controller. Having the CA active in an unattended sit...

...I like 2 button digital Aux more paired with 3-speed switch. Cycling through the Aux functions would have some pretty bizarre effects on operation because of the interpretation of the other releated settings that configure those different functions. Here the option would instead to allow it to b...

A pretty surprising result - but very cool.
Thanks for posting back!

The LED backlight is driven in series with the CA electronics and gets brighter with increased current draw. This strongly suggests that your pot is wired improperly and going to the high setting is shorting out the +5V supply. Recheck your wiring - I'm pretty sure you have the wiper and one end int...

i went to the Spoke length calculator but allot of the terms and acronyms baffle me

Which spoke length calculator and what terms did you not understand?

Use this one - it has explanations on the same page:

I have opened up the CA, I can see r18 is toast, and I assume the op amp is also toast. Is anything else likely to be damaged or should I start with just replacing those two components. You paid for Tech Support when you bought the device. Use it. Grin has experience with every CA mishap you can im...
