I recently got a 2000 Insight with 180k miles. When driving the car home after about 175 miles the IMA light came on and the charge/assist stopped working. After a little research I pulled the #4 fuse to reset the IMA and it worked ok again for a while and now it has happened again. After driving the car for a few weeks now I have been paying close attention to the charge/assist gauge, I have noticed that it will charge fully at times but will rarely go half way on the assist. And many times it will assist for just a few seconds and then fall back to nothing. I lot of times it "kicks out" just when you fell you need it to work. My question is. Is this a battery or controller problem?
