One Prius Gen2 Inverter + one Prius Gen2 DC Motor Controller + instructions = Control of Current to DC Motor
correct:)
I have my Prius Gen 2 inverter installed.
My 167 volt pack connects to the inverter. Batt Pos to Inverter Pos, Batt Neg to Inverter Neg with working pre-charge delay.
Pack voltage+ from contactors to positive input on inverter shows 167 volts
Pack Negative from contactors connect to both inverter negative high voltage and motor negative connector.
My PRIUS GEN 2 DC MOTOR LOGIC BOARD V1 has:
Inputs on CONN1 12 volts+
Ground
5 volts+
THR (throttle signal from accelerator pedal)
REV (12 volt input when backup lights are on)
BRK (12 volt input when brake light is on)
Ground to chassis ground
Ground to chassis ground
Outputs on CONN2 MG1 (PWM signal to MG1 pins 4,5 and 6 on inverter input of Prius Gen 2 32 pin connector)
MG2 (PWM signal to MG2 pins 9,10 and 11 on inverter input of Prius Gen 2 32 pin connector)
Ground to chassis ground
Ground to chassis ground
PRIUS GEN 2 32 pin connector
pins 4,5 and 6 connect to output MG1 on DC MOTOR LOGIC BOARD
pins 9,10 and 11 connect to output MG2 on DC MOTOR LOGIC BOARD
pin 14 (GSDN) connects to 12volts+
pin 16 (Ground) connects to chassis ground
pin 25 (MSDN) connects to 12volts+
PRIUS GEN 2 C5 6 pin connector
pin 1 connects to 12 volt
PRIUS GEN 2 "B+" connector
wide blade connector to 12 volt battery positive (for charging while running)
PRIUS GEN 2 2 pin connector (next to 32 pin connector)
red to 12 volt+
black to chassis ground
Power Up Sequence
1. Ignition key to run position
12 volt power to Gen 2 2 pin connector
12 volt power to Gen 2 DC MOTOR LOGIC BOARD
red light is on and Throttle input is at .6 volt
Positive contactors to battery pack closes
7 second delay and Negative contactors to battery pack closes
power brake canister vacuum pump starts
power steering pump starts
Test
Press on accelerator pedal and Throttle input is at 4.6 volts
Release accelerator pedal and Throttle input is at .6 volts.
Prius GEN 2 "B+" output has 14.5 volts to battery
Prius Gen 2 32 pin connector, pins 4, 5, 6, 9, 10,11 all show 15.5 volts.
All six phase connectors ( three for MG1 and three for MG2 show 0 voltage
No heat from inverter or motor.
No smell of burning wires
No indication that any component is upset with me.
Question
What do I look at, test, probe next.
Thanks to all who have contributed to me thus far.
I don't know what to do next.
I need more guidance.
I like to do things myself, I am stubborn but know my limitations.
I need a little more help.
Thanks

I'll post pictures soon.
