One step forward two steps backwards. I need a win.
Sorry just venting now
I do have the voltage differential on pins 1 and 2 and across the two big lugs on the contractor.
I have something hooked up wrong here. This controller does the same thing. Working with the serial converter.
Hmmm… It was a good thought. Let me stare at the inputs again.
How about changing out the cluster?
That is next I guess.
Changed the cluster this morning. Nothing…Cluster lights up I can toggle through things but contactor does not pull in. This one does not care if the serial converter is pulgged in or not.
I checked the voltage at the Cluster guys power converter and it’s spot on. I got to thinking last night that his voltage going into the cluster was too high…I was wrong.
I am at a loss. Which admittedly doesn’t take much.
Nothing…
Be mindful when using assessments like this.
From a diagnostic standpoint this is still something-
Cluster lights up I can toggle through things
but contactor does not pull in.
What does this mean? You can step through some of the menu items?
Does the display show you anything new?
Are there any error codes?
Do any other direction selections work?
I can change MPH/KPH, toggle between trip and total miles, cleared the trip odometer.
Cluster sees the key switch changes.
I did see a 51 error code pop up but I don’t know if that was stored from the other Think. It seemed to clear itself but maybe I got button happy.
Cluster sees the key switch changes.
This one shows the switch selections? F, T, and R?
OK. Let’s check for power at the back of the Cluster. P7 is contactor power.
(Did we determine it was a 12v or 72v coil?)
Also look for power out related to the key select. 3, 4, 5.
Depending on what we find here we can move down to the controller.
Failure to precharge. Important for coil to pull in.
Complete Byrons tests first, but:
Check voltage at B+ on contactor. Or both sides of contactor if it’s easier.
(I think I read this)
Supposedly this Cluster has the ability to go back and step through controller memory? This -51 may have been a past error.
If this is the case it is communicating with the controller via Serial comm? We can purposely throw a -11 or something.
72 v coil
My son has a tennis tournament today. I will report back with findings.
Thanks again for sticking with me
Cluster pin 7 is 87.3
Pin 7 on the cluster is a constant 87.3 R, T or Drive. 87.3v
I was just probing pin 3
Off 14.5 volts
Rev 15.47 volts
Turf 28.6 volts
Drive 28.18 volts
“23v on pin 15
Plug converter into Data Port
13.6 volts”
I’m not even sure where I got this now. The contactor was pulling in before.
I will try and plug in the serial device.
I got nothing with or without the serial device with this cluster and controller.
Why am I thinking that the cluster needs a spoof too. Probably wrong, and I am grasping for answers without having the knowledge.
My fsip D2 pin-out is wrong. What controller is that again?
My previous suggestions were mis-guided.
I would still start with P3.
Does someone know it P3 is switched 12vdc in?
Or switched dc out of converter?
If you need to test it, disconnect P3 at controller to see if it has 12v from the car or from the controller. Either way it’s wrong reading too high.
