The code 70 i was having ended up being a traction card proplem. RP the card and the proplem was sloved

hola amigos, un cordial saludo, tengo una situacion con el voltaje de las luces, me esta llegando 36 voltios, donde se encuentra el dispositivo que me permite reducir el voltaje a 12 voltios gracias

hi sr, have a good day, i have a situation with the ligths volt, its arriving 36 v, i need to find the dispose to convert to 12v, thanks

funny, I spend yesterday fighting code 70!! it came in, I clean the logics and sent it back out. Come back 10 minutes later same problem. Played with then currnent sensor. come back a few more time. ended up being a bad logic connection. Had to really scrub the pins.

I agree with justin codes like that are very rare clean the truck bow off all, the electrical & unplug the batt & turn the key off - then plug it back in & turn it on again.

See what happens

sometimes ev100 gets a problem with "microscopic oxidation" on the pins in the plugs and in the card itself
those 2 wires are for the shunt (current sensor)
the sensor works because it has a very slight resistance across the bar (almost unreadable to a standard multimeter)
the card is measuring the voltage differance between these two wires
clean the plug and the pins in the card with nonconductive electrical cleaner and get a good dialectric paste
ge sells a "plug service kit"( for cleaning and sealing the plugs) available from flight systems industrial products in carlisle pa
or your local mitsu dealer sells this kit too with a specail dialectric the ge reccomends for the plugs

this sensor is not on the main scr panel it is on a sub panel
it is a flat bar with the green and yellow wires (main current sensor is kinda L shaped on the main panel)
you can recognise it as its 1 rectifier(7 rec) that is the same as the 3 and 4 rec also has a shunt bar (with the grean and yellow wires) and the rb contactor it is all mounted on a small heatsink base separate from the main traction and pump panels

past all that though if you have power to the two pins in the pa plug then u might have an internal disconnect in the card in that case get a rebuilt card as they are not very expensive and there is not much left in that error code to check (flight systems has those cards probably ready to ship)

The next step is to check for battery positive on those same 2 wires.
The safest way to check would be to disconnect the battery, then measure the ohms from the plug a terminals to both sides of the traction fuse.
If both wires make it to both sides of the traction fuse, then the problem gets tougher. If they only make it to one side of the fuse, then it's the fuse.

Mike,

Thanks for taking time to assist me. So far I follow your directions and no solution. Both wire 21 and 22 are in spec. Beside code 71 there are two icon displaying on the dash one is the book and the other is the wheel.

Right on the ev100 card in the back.

There will be 3-4 plugs on the card.
2 big ones, and 1-2 little (depending on options)
'PA' is the one you want, it'll be the outside little plug.

If your unit has scr hydraulics, then there will be 2 cards, the traction card is the one on the left.

Thanks Mike. Can you please tell me where the location of the connector?

Code 71 is for the regn current sensor.
The control card is seeing an open for the green wire that runs from the card to the regen sensor.

The sensor is very low current and voltage, so it's liley just a jiggly conection at the plug.
It's wire 21 at the small outside plug.
Simply unplugging it then plugging it in will likley fix it.

If not, you'll need an ohm-meter to test the wire and the sensor.
There should be ~0 ohms between wire 21 and wire 22 on the same plug.
