A friend of mine has an 86 FWD coupe, and the digital dash is acting up. It doesn't happen every time,but on occasion the dash won't light up. Shut the car off, disconnect the battery for about 2 minutes, reconnect and all's well for a while. Anyone BTDT with these. Any input is appreciated. TIA. Charlie Lamphier 86 5ktq 84 5ks 97 Miata
