Excellent example.

I'm not ashamed to say I did this once by accident. Maplin precision gold multimeter. Had been using it on 10A current at home the night before to monitor an RC car battery charger. Got to the car at 6AM in the morning when I was half asleep and it was dark and it wouldn't start so I went back in, got the DMM and went back out to check the battery voltage. Now the meter had the 20V DC and 10A ranges at opposite ends of the range switch. The little black mark on the end of the range switch had worn off. Stuffed it on 20V DC I thought (no - 10A), touched the battery terminals. Big spark, probes welded on, one of the DMM leads disappeared in a cloud of smoke in two seconds flat.

You have been warned.

Good things we have now:

1. Probe alert.
2. Fused 10A ranges with proper fuses. Not pansy ones.
3. Probes which fuse before catching fire.
4. Cars without Lucas electrics.

(Edit: add point 4)

Tautech, I'm with you, I've fallen for other posts by the OP before and the more I think about the more convinced I am that it's just a big windup and as such is a pure waste of time responding as the OP seems incapable of of providing any coherent information or sensible response.  :rant:
