Hello all, today I bought a very nice 914 that had what looks like a battery fire. I think that because the battery has melted in half and the sail pail shows signs of smoke. I bought it from a donation yard so the owner isn't around to question. So I bring it to y'all, What would cause this and how can I prevent it in the future?

It's a late model. The coil was on the tin. Often the tin will rip and the coil will no longer be firmly held in place. If the coil rotates and contacts the tin it will short to the engine tin. If you keep cranking it trying to start it, the battery cables melt and it will even burn away the sheet metal where the negative cable contacts the sheet metal above the battery. Often a good bit of harness will be melted.
Not too hard to fix. Depending on the extent of the damage. Contact Bowlsby for a replacement harness. As for prevention, securely mount the coil. |

Believe it or not, I almost did the same thing to mine... in fact, before McMark left for Grand Rapids, he repaired the burned out negative post and replaced it. Been a long time since mine was a Type IV with late tin, but I do remember things. Experience is a bitch of a teacher. This almost went up in flames! Attached image(s)
