Subject: Re: Europa-List: EIS versus Steam Gauges
If you fit an EIS just make sure you have a means to isolate it from the
main bus during startup. We have found that if the EIS is not switched off
on startup (starter cranking) the spikes often scramble the memory and
alarms which take about 20 mins to reset again. The worst thing is the reset
ususlly causes the screen contrast to go to zero and then everything becomes
impossible to ajust until the screen contrast can be increased (ie: the
display appears to go blank).
I would suggest that a momentary disconnect button is fitted close to the
starter switch so that temporary isolation can be effected, though a more
sophisticated setup could include an isolator solenoid connected to the
starter solenoid.
An manually operated isolator switch (which is what we have) is not a very
satisfactory solution as its very easy to leave it on during startup and
also easy to forget to turn it back on after startup.>>>>>>>>>
Hi Carl,
I think there may be a glitch in either your circuit or with your EIS since I am
sure that the unit is designed to accept any start-up spikes. My Grand Rapids
EIS stays on during the start with no problems and I am not aware of an EIS
owner having the problems you describe. Have you discussed the problems with
Greg
Toman at Grand Rapids? I have always found him to be most helpful.
