75% of all electrical problems on a 2cv come from earthing. To check if earthing is the problem, take a wire with a crocodile mouth clamp on each end. Connect one end to the earth wire (or metal housing) of the thing that isn't working and one and to the - connection of the battery. If it works now (fiddle with the wires a bit) it's an earth problem.


Fuel gauge isn't working:

Either the connection near the front of the left inner wing is loose (from removing the rear bench) or you have bad earth. The earth wire runs from a connector of the fuel gauge sender to on of the rear bolts holding the tank. To check:

Checking and rebuilting the brakes

Honing of brake parts is done with a tripod with spring loaded moving arms with small stones on the ends. This device is fitted in an electric drill and used at high rpm.

When removing brake components, secure the brake pedal in a lower position, this keeps the brake system from leaking empty.

Some standard checks:

Rebuilting front brakes, discs front

Rebuilting front brakes, drums front

Rebuilting rear brakes

Removing the master cylinder

Rebuilting the master cylinder, dual circuit.

Rebuilting the master cylinder, single circuit.

Removing air from the system (bleeding)

Adjusting drum brakes (front and rear)

Adjusting the handbrake, drums front.

Adjusting the handbrake, discs front.

Trouble shooting

Starting or running troubles:

90% of the cases has to do with the ignition. Most of the time the timing is wrong or the points and or capacitor are bad.

The following parts should be in perfect condition:

With all these parts replaced any A-type should be a reliable starter at any time during any season.

What to check when the car won't start:

The engine will start but hickup (especially when revving) and not have much power (stall when trying to drive away).
