Solar panel -VAS 6102 A-

3.6.1

Description of solar panel -VAS 6102 A-

Solar panel -VAS 6102 A-
Solar panel -VAS 6102 A- supports onboard supply and prevents

spontaneous discharging of battery -A- .
Solar panel -VAS 6102 A- achieves max. voltage of 14.3 V and a

maximum charging current of 255 mA.
Use of the solar panel -VAS 6102 A- is permissible for charging

all rechargeable lead or lead-gel batteries.
Solar panel -VAS 6102 A- is connected to diagnostic connection

in vehicle.
A green LED is integrated in the frame of the solar panel -VAS

6102 A- to indicate that the panel is functioning. The brighter the

LED is, the higher is the charging current.
The integrated electronics prevent battery -A- overcharging.

The solar panel -VAS 6102 A- is attached to the interior mirror

-1-. The underside rests on the dash panel -2-.

Note

Solar panel -VAS 6102 A- is not allowed to lie fully on dash panel.

It is only allowed to be placed on dash panel with the bottom edge

for support. Placing it fully on the surface can result in discolou‐

ration of the dash panel.

panel -2-.

Note

Solar panel -VAS 6102 A- is not allowed to lie fully on dash panel.

It is only allowed to be placed on dash panel with the bottom edge

for support. Placing it fully on the surface can result in discolou‐

ration of the dash panel.

– Pull the fastening wire together until the solar panel -VAS 6102

A- is close to the windscreen.

– Plug the connector of the solar panel -VAS 6102 A- into the

diagnostic connection of the vehicle. The panel is connected

in the same way as the vehicle diagnostic, testing and infor‐

mation system -VAS 5051B-

 .

– Test the solar panel -VAS 6102 A- to make sure it is functioning

correctly. The green LED must light up.

Totally discharged batteries -A-

WARNING

Danger of injury! Observe warning notices and safety regula‐

tions 

⇒ page 2

 !

A battery -A- is designated “totally discharged” if the no-load volt‐

age is less than 11.6 V.

WARNING

Do not test or charge batteries -A- whose magic eye is “col‐

ourless/light yellow”. Do not slave/jump start the vehicle!
Danger  of  explosion  when  checking  and  charging  or  slave/

jump starting
These batteries -A- must be replaced.

Caution

♦ Totally discharged batteries -A- freeze prematurely.
♦ Frozen batteries -A- must no longer be used.

3. Charging battery A     

63

Batteries -A- that have not been used for a long time (vehicles

that have been stored) self-discharge.

In totally discharged batteries -A- , the electrolyte is comprised

almost entirely of water because the acid content is so low.

Totally discharged batteries -A- sulphate, that is, the entire

plate surfaces of the batteries -A- harden.

If a battery -A- is recharged shortly after it has totally lost its

charge, the sulphation will dissipate.

If these batteries -A- are not recharged, the plates continue to

harden and the ability to recharge is reduced. The result of

which is a reduction in the battery output.

Totally discharged batteries -A- in vehicles before registration

must be exchanged prior to delivery. Preliminary damage can‐

not be excluded.

Carry out following procedures:
– Check no-load voltage of battery -A-
