Went out to star the b7100 and it would turn over a black smoke came out. I checked the glow plug indicator to find it not turning red. So I figure it went being I could not see in the hole very well. When the new one came one I pulled the old one to find it still intact. I went head and put the new one, being I had the old one out already. Then when I turned the key to heat it the new melted in half a second. I then took it out and put the put one back in. Turned the key and nothing. I mean I can turn it to start and it does turn over and the black smoke comes out but I’m not sure what is going here. The old indicator never gets hot. Any help or idea would me great. Thanks
