Alright, I'll try to keep this simple. The last several days my Disco II will start right up half the time, and the other half it won't. Until today, the times it wouldn't start right away, I would wait a few minutes and try again and it would start fine. When it doesn't start, it turns and turns like it's trying to start but doesn't fire up. After a few seconds of holding the key in III position the "turning" sound of the engine begins to slow and I let off. I noticed a little corrosion on the positive connector to the battery, cleaned and lubed it, but that hasn't seemed to make a difference. This morning it started fine when I left for work, but now it's time to go home and it won't start. The "turning" sound of the engine has slowed enough that I know I'm beginning to drain the battery. Any suggestions???
