What is Code 05 Caterpillar Electric Forklift

Post by Eric »

Code 05 on the dash of a Caterpillar electric forklift and it wont move and no hydraulic functions. The truck wont go forward or reverse and no lift or tilt. After doing a PM and blowing out the truck the code came up on the dash now it wont move. Is this a common fault code and what could be the problem?

Hello and welcome to fixaforklift!!

Well code 05 on a caterpillar electric means power circuit not complete,

This can actually mean a couple of things
The most common one is the power relay that is located right under the brake master cylinder,
I have found that once dust get inside you cannot blow it out and need to replace it it has three wires on it a red one yellow wire and green wire,

There is a relay that look identical next to it but that one has different wire colors on it,

The other thing it could be is the brake relay located right on the floorboard, it has three pins on it and only two wires, the yellow wire should be hooked up to the top pin and the red wire should be hooked up to the furthest bottom pin, this has to be connected like this or else it will not work,

These are both part of the power circuit they need to be corrected in order for it to complete the start up cycle

Thanks ! Do you happen to have a picture of relay location ? Or a new one so I know what it looks like. A part number would be great too. Thanks again .
