komatsu pc200-3

I have a komatsu pc200lc-3. Below the battery warning light on rh side of monitor there is a red lamp flashing. There is no emblem beside it to tell what it indicates the warning for. If anyone knows what I should check please post. The hour meter has not worked since I have had the machine, but the clear indicator lamp on it always flashed. It stopped flashing and may have stopped when the light below battery ind started flashing.

thanks for any help.
