Charger repair 12V SCHEIBER caravan

And if they were repairing rather than throwing and change? Rediscover the pleasure of the repairs yourself. How to diagnose a problem or find spare parts? Repair itself is way to save money generally!

Charger repair 12V SCHEIBER caravan




by Abalone59 » 26/07/19, 18:42

Hello everybody

I come to you to try to troubleshoot the battery charger that equips the caravan arranged by my parents-in-law.

This is a charger brand SCHEIBER 63.306.0
220V-12V

The indicator lights up.

I know how to handle a multimeter but my electronics courses are far too far to remember the method of troubleshooting. Coil, Diode Bridge, Rectifier ... Waves
memories...

Here are some photos to start hoping to get your precious help.

Thank you in advance.

Given the very basic design of the machine, it is a charger that is more likely to screw up the batteries than to recharge but good.
Given your level in electronics, just measure the voltage at the secondary of the transformer (with all the precautions of use level security) you must have about 16VAC to 18VAC between the middle and each end (or about 32 to 36VAC between the 2 ends) and if not, a quick check at the primary level (paying even more attention)
If the transformer is dead then: https://fr.aliexpress.com/item/32962306 ... b201603_53

If it is still good, it is better to get closer to qq1 in your personal or professional environment who could look at the electronic card in more detail
