Repair Instructions#


Typical car battery

Jumper cable

In emergencies a battery can be jump started, by the battery of another vehicle or by a hand portable battery booster. Generally, this is not recommended on newer, computer-controlled vehicles as damage can easily occur.

To jump start a battery the hoods of both cars need to be open. The car that provides the jump should turned off. Now one end of the jumper cables have to be clamped onto the car battery of the car providing the jump. The positive (or red) clamp should be connected to the positive(or red) battery post first. Afterwards the negative (or black) clamp can be connected to the negative (or black) post of the battery.

Now the other end of the cables can be connected to the other car's battery by installing the positive clamp onto the positive post of the dead battery. The negative clamp should be connect to a clean ground on the engine of the dead car or directly onto the negative battery post.

Now the car that is doing the jumping have to be started - now the charging begins. After 5 - 10 minutes turn off the engine of the car that provides the jump.

Afterwards the dead car should start again. If so you can remove the cables in the opposite order you connected them (negative before positive - former dead car before providing car). If the problems still exist the battery should be changed.

IF Starter = does not turn over THEN Flat battery = P5
IF Starter = turns over THEN Flat battery = N4
IF (Engine start = does not start OR Engine start = engine barely starts) THEN Flat battery = P5
IF Engine start = engine starts THEN Flat battery = N5
IF "Check: Battery." = ok THEN Flat battery = N7
// If Battery check is not ok establish Flat battery
IF "Check: Battery." = not ok THEN Flat battery = P7

Flat battery { "Check: Battery." = not ok [++], Starter = does not turn over, Engine start = does not start, "Num. Mileage evaluation" > 0, }

Flat battery.description = The battery is flat and should be charged or replaced.
