Hello my name is ***** ***** I will be assisting you with all of your vehicle questions today. Give me one moment while I review your question and come back with a answer. Please be aware I do not know your skill level or abilities so I will be asking a lot of questions and in a lot of cases we will respond to each other quite a lot before we find a solution. As far as phone calls are concerned that is the system prompting you, not me, and they do cost more money, I prefer text but in some cases a phone call is required.

That would be a bad idea, if it comes with a 3 amp fuse its there for a reason, if your trying to power something separate that keeps blowing fuses I would suggest and power inverter or just a inline socket thats fuse protected and can be run to the battery for extra power.
