My digital tach/speedo gauge (aftermarket Cyberdyne unit) acts "funny" when the 4-way flashers are turned on. The gauge is back to normal when the 4-ways are off.
The only thing i've done is to install a new turn signal flasher yesterday. The gauge is not affected when either of the turn signals are activated.
Not a big deal right now, just wondering what you thought it could be?
