No - this does not apply - you are using a new V3 shunt not a controller DP connector...Michall2008 wrote:Instead of connecting the CAs ThO to controllers Thi, connect brake signal pin to controllers Thi ?amberwolf wrote:some older controlelrs' ca ports put th e ca trhottle line to the brake pad instead of throtlte pad. i had to fix mine.
Here's a link to a similar controller/wiring - no surprises. Yours seems to have ebrake wires as well. From eBay:
Okay. So it seems by (2) and your previous post that the CA ThrOUT voltage on the blue/green wire junction of CA ThrOUT and controller ThrIN is appearing relative to the CA Gnd but not relative to the controller throttle Gnd. According to (3) the throttle Gnd and CA Gnd may be the same. Puzzling. (Actually looks like either a bad blue/green connection or a different ground reference - neither of which seem likely...)Michall2008 wrote:1. Its 1KW/36V YK43 brushed controller
2. The voltage is always zero
3. The same thing here, always zero
4.As a load im using 2 halogen bulbs, pulls about 900W at WOT. Start glowing at 1.8, WOT is 4.83 (I'm using a not very accurate voltmeter so +- 0.1v)
By (4) it looks like the CA can be adjusted to yield the necessary voltages. (Good)
Hmmm - You did not show the shunt connections wired into your battery red/black (+/-) leads on your diagram, but I'm assuming that the shunt is wired in since the CA has power.
Unfortunately, (1) pretty much puts me in trouble with no brushed controller experience... I can think of some things to try, but it would just be guessing and experimenting. The fastest path to a solution is probably for you to email the support folks at Grin Tech and just briefly point them to these posts which describe your problem and have a bunch of useful information to jump start the discussion.
While you are waiting for a reply, you might hook up the throttle to the controller again and verify that the CA measures Watts on the main display as you advance the throttle. This is a small thing but it will ensure that the shunt and CA power connections are 100% correct.
EDIT - Ah! I missed Justin's post - and your response. Good news! Lesson - don't post before morning coffee...
