Sargent 155/ctek: high voltage and 'v' function

Hello all. I have a question but I am absolutely not an expert.

I have has a similar problem to the one described here: High Voltage Issue on CTEK/Sargent EC155

I had it looked at by the converters and they sorted it in the way that thread shows. It's been spot on for 2 years. However, over the last month the problem has returned.

What happens is when the engine is running the we voltage sits at 14.7 with 'l' selected on the control panel unit. But sometimes it spikes to over 15 and it goes mad with lights and beeping. There appears no pattern to when it does this.

When set to the 'v' on the control unit it sits at 13ish volts


My questions are 1: how could this problem reoccur?

2: if I just set it to 'v' and drive will that flatten the van battery? Will it charge the leisure battery?

Thanks in advance
