Just as the title says, how much voltage is too much?  My current bench power setup is no longer providing 12-13v of power.. I'm trying to do some testing on various code for my ECU and would really like to get up and running as soon as I can.  I have another power supply I can use that provides about 2-3amps of power... but 15-17volts.  I know the ECU can handle 14 volts without issue, but would I be safe in the 15-17volt range?

Thanks!
