Back to square one

After installing a spare current sense board in the ute's speed controller, it tripped with an earth fault again on Sunday.

Might have to get hold of another motor for testing.

Walking to work does me good, except when there is a massive dust storm over Sydney!

Hopefully the ute is fixed

The speed controller has been stopping with an "earth fault" intermittently with increasing regularity.

After talking to the Danfoss service guy, thanks Gavin, I installed a similar current sense board as this is where the problem seemed to be. The ute ran fine for about a week.

Last week I took the original board and soldered in a resistor array that was in a socket and re soldered the current sensors then replaced the board into the ute.

I have been driving for about 5 days, so far without fault. Lets hope that is the end of the problems!

This Servcei book entry creates a CMIME and BrowserConfig service book entry that uses the data channel instead of BES.
