Ford Fiesta MK6 02 TDCi + WAECO Power M50U WAECO + TB-08G-12 TROPICOOL board bar
The voltage monitor blinking constantly and does not supply power to the board bar when it is plugged in before the engine is started.
And although the TDCi (diesel) anyway a stronger car battery is installed and I had this recently again charged a maximum in a battery charger.
