Jenn Air lp grill won't light with the ign...

I just finished cleaning our starter on our jenn air. Over time, corrosion, rust and battery acid builds up on both the coils on the lid (positive side) as well as in the battery chamber and negative tip inside the chamber. I used sand paper and sanded the coils in the cap and the chamber. The coils need direct connection to the battery to create the charge. There are no instructions on this that I was able to find. I figured it out after about 3 hours of fussing with it. It worked immediately once I placed the battery back in. You may also need to clean the electrode tips near the burner. I used a q-tip. Hope this helps.
