“OMG!! This guy is like Magic - he was so calm and really you could see him THINKING things through - like a neurosurgeon!! We have a VERY complicated vehicle - 1988 Volkswagen w/ a Subaru conversion - two battery systems and LOTS of complex (hard to get to) wiring!! He just showed up when he said he was going to and methodically went through the electrical system! Then he FOUND the issue and SOLVED the problem. We are both SO impressed and grateful for skills & calmness. We were a long way from home ...impressive work truck with all the bells & whistles...super clean and super SMART dude!! Thank you Josh...we appreciate you”
