Wanted to thank everyone for such an awesome resource, after my mechanic told me that my main battery was bad this form has the information I needed To confidently save some much needed money, so kudos to you guys. Below is a list of my loaded and unloaded battery voltage readout. Please tell me how the voltages look to you am I right that my mechanic was incorrect in his assessment that the HV battery was wrong, i believe it may just be the 12 battery? Thanks for your help the first number is the reg voltage the second is under load of a 7v 5.5watt light bulb.
