I have purchased a second hand A65 plotter with DSM25 sounder module. The sounder module is showing an alarm which is stated as 'Transducer Sense Failure'. I have purchased a new transducer and this made no difference, so I have to assume it is an issue with the DSM module itself.
Does anyone have access to a DSM25 that they would be happy to help with a bit of diagnosis? i.e. plug my A65 into your DSM and my DSM into your A65 to try and prove a system issue?
Or, if anyone has a DSM25 they want to offload / sell, and willing to do so on a sale or return basis??
