Noticed this before a little afternoon run... Electrical system is new 62T courtesy of jet ski solutions remanufacture, battery is 3 years old would barely turn over my spark a few weeks ago due to winter but I recharged it. Cranks perfectly fine. Looks like an overcharge or a cell out of balance that was overcharged? Could fuel have leaked and caused it? It seems the cover pins the caps down. Is this safe or useable? Thanks!
