They made my day which wasnt going well prior to their arrival. Thank you guys

We cannot speak highly enough of YSS. Don Gulliver has a wealth of experience and is genuinely interested in solving problems. He and his crew problem solved issues we were having with our engine alternators and also our diesel heater. He modified and greatly improved the performance of the alternators, in addition to adding several safety features in the battery banks. He overhauled the diesel heating mechanism which entiled much problem solving and he did not give up until the system was running perfectly. In addition he suggested several improvments to the battery monitoring system. The team are professional, pleasant and reliable. We wholeheartedly recommend them.
