Expbus And Gauge Readings

Question for those who installed the Expbus.

Is anybody getting funny gauge readings when
they switch the ALT on?

I have UMA/Vans analog gauges.

When I switch the ALT off they seem to read fine
and sometimes when the ALT is on they go back to normal.

I thought it might be when the ALT is charging it's giving
off a strong magnetic field around the ALT wire where it
attaches to the expbus.

I have the small version model ExpBus2V.

I tried many different grounds and even routed the ground
direct to the battery with the same results.
