Hi: Thanks for coming to Just Answer with your question. My name is XXXXX XXXXX perhaps I can assist you with this. How many batteries did you swap out and what are they........6 volt or 12 volt units. What circuit is that fuse for if you know? Get back to me and I will help you resolve this. R.J.

I changed one battery, 12 volts. It's the main fuse on the generator that blows imed. after hitting start (it will allow you to prim it).
RV Mechanic: Randall, RVIA Certification replied 8 years ago
Was it doing this before you change out the battery? Are you sure you have the battery hooked up correctly? Double check your wiring. Did you charge the new battery before trying it? Many new batteries aren't fully charged and this will allow the amperage to be higher on the draw and this blows fuses. Let me know what you find. R.J.

Ok. I only changed out one new battery because it had a bad cell. It is hooked up correctly, however I did not charge it prior, as I assumed it was charged. I will charge it now & retry. How do I reach you (directly) back to follow up with you one ay or another?
RV Mechanic: Randall, RVIA Certification replied 8 years ago
Just Bookmark this page and you can come back to it at any time in the future. Be sure that you hooked up the 12 volt batteries in a parallel hookup which is positive to positive and negative to negative to maintain the 12 volts. In series would give you 24 volts and blow fuses every time. I will watch for your post. R.J.

We had the battery tested (single 12 volt battery) It tested 13.16 voltage 695 cca. Again we tried it & blew a fuse. Any additional suggestions? (guardian generator).
RV Mechanic: Randall, RVIA Certification replied 8 years ago
The next most probably cause is that the start switch on the genset is bad or that the starter is bound up or has a short in it. I don't know that we have any techs on site that have Guardian expertise.........Do you have any local techs that might? R.J.

I appreciate your help but contacting a local tech was exactly what I was trying to avoid. Is their a way my question can be reposted to see if there is a Guardian expert available or for another tech to try & brainstorm with us? At this point I am not 100% satisfied.
RV Mechanic: Randall, RVIA Certification replied 8 years ago
Not a problem.........I did ask the Onan tech and he doesn't do these. The is one other tech that might but he isn't on here all the time. I will opt out of this and you can see if someone else responds. R.J.
