Hi Paul,
I had a Link10 many moons ago and now a LinkPro. I have not seen the
problem you are experiencing.
There is always the loose wire possibility, the very small connector on
the Link10 is problematic.
After that, I would suggest looking at the input to the DC-DC, are there
any input voltage dips that are outside the spec of that unit. What are
you using for the DC-DC?
Since your symptom is that you are losing the isolated twelve volts into
the Link10, then that points to the DC-DC, if the connections are good.
Some DVMs will store a min/max value, you might be able to see what's
going on that way.

My Link10 is going through a reset at random times when the inverter is
switched to drive. I've looked down to see the display switched to blinking
volts more than once. This never happens when I'm discharging the pack with
the load bucket. The system is turned on to drive when I'm using the load
bucket, but the drive is not active, switched to park. I've caught it in the
act of resetting twice now that I know to pay attention. It will be displaying
the current AH reading, then I switch to 'D', when suddenly all the Emeter
front panel display goes dark and then returns to blinking volts, like a power
failure. The Emeter is powered by an isolated DC/DC converter. This is an old
electricar S10 with a new RMS PM100 drive inverter. The only thing I can think
of is that the inputs to the prescaler are different lengths and don't run next
to each other for about 1 foot. I'm thinking that I'll reroute the short wire
to follow the long one exactly to reduce the loop width
,
but it is a high voltage prescaler so I wasn't anticipating too much noise
would make it through at a magnitude great enough to cause this sort of
problem. The current shunt wires are twisted together from the shunt until
they reach the Deutch connector, along with the voltage sense wires. The other
side of the Deutch connector is shielded cable going back to the dash.
Since the front panel says Link10, I'm thinking that it should have the EV
filter already installed. Has anyone added extra filtering to mitigate noise
getting into the Emeter?
thanks,
Paul Wallace
still working on the S10
