Hi Guys
My wife bought this little handheld vacuum cleaner to me this morning complaining that it runs for a few seconds and then stops, but if you release the trigger and then go again, you get another few seconds and then a repeat performance.
I've done some googling and this is apparently a common fault to do with a 'Hall Effect' sensor which is activated by a small magnet in one of the filter housings. Certainly, I can make it run continuously by hanging a large magnet nearby.
I found this https://www.is-beer-a-vegetable.com...Handheld_vacuum-_cuts_out_after_a_few_seconds which advocates removing this hall effect sensor ( TLE 4913 ) and bridging contacts 1 & 3. I've done this but nothing doing .. .. however, the datasheet for the TLE4913
**broken link removed** states that pin 1 is Gnd; pin 2 is input; pin 3 is output; That being the case, then bridging pin 1 & 3 is putting output to Gnd, but if there is no input - no output ? Right ?
I'm tempted to bridge pin 2 & 3 - input to output but I don't know that the voltages match .. .. .
Anybody got any previous experience with these things ??

PS There is a rumour that if I fix it, I may be allowed to forsake my diet and have a cheeseburger & chips, but I wouldn't hold your breath !!
