Heinzman charger problem

[Robocol]

The 24v charger for my Heinzman black plastic battery box blew up a few months back and I have not been able to find another. It could be repaired but a couple of small resistors on the board are burnt out making it impossible to determine their value. I have all the replacement transistors etc but need to know about the resistors. Heinzman will not give me any information. if you have one of the chargers could you please help by either photographing the board or telling me the colour code of the bits if I send a diagram of what is burnt out? Or, if you have a 24v charger you no longer need please let me know. Any help would be very much appreciated as I am somewhat disabled so cannot use the bike at all until it is fixed.

Thanks

Colin

Pedicab Rickshaws - Cycles Maximus Trikes for the 21st Century (+44 (0)1225 319414) use a 24 volt system. It might be worth giving them a call.

Also, the current UK distributer is Dr Andreas Schroeer of Twike.co.uk (the previous UK distributor was Peter Walsh of emotivecontrolsystems.co.uk).

Good luck!

Kinetics have been very long term agents for Heinzmann and know plenty about them, so definitely worth contacting Ben there for advice:

Thanks for the replies. I did contact Kinetics but got no response. I am not impressed by Heinzman after sales service! I will follow up other 24v chargers and see if I can cobble something together.

Thanks for the link but I am not sure that battery is up to the job. It says the maximum continuous discharge current is 10A and the max is 10A. From what I remember that is not enough for the Heinzman hub.
