i have narrowed the tripping of electrics to the hair drier. but cant seem to find any short in the drier or element. the...

sounds like something wrong with the mainboard. green light should be on on charger uuntil connected and should flash red if charging. open up and check the battery is charged ie approx 37v. if charged check red black lead switch is working. check resistance across battery leads on mainboard o is oshort cct 10meg ohm is what it should be. you can buy a mainboard for approx 30 quid

if u opened it you might have shorted something. i was given one and the power terminals where short ccted on mainboard. check resistance across 2 nain rails near power leads, 4 capacitors in a row bridge it.

i, like many others, ripped off the battery connector by being to rough disconnecting the battery. i cleaned up the surrounding area with isopropyl alcohol and was worried about how to re-solder, with heatgun, or iron, without melting the plastic on top. so i decided to go for conductive glue u can get off ebay. worked a treat. just dab it on connectors with a toothpick or similar small item and u have about 30 seconds to line it up, then let it set. i just love this new conductive glue for small parts as i also used it to fit a new little blue inductor near the battery connector.

the batterry screws are nearly always torx screws, they are tiny star shaped and no 3 is the 1 to use for iphones, i also bought a no 2 torx screwdriver as it is for blackberry torches only. if i keep using phillips or flat heads of various sizes u will end up shearing the screw and it will be to smooth to grip.

first thing to check is always the plug fuse. something a lot of people forget to do. always change the fuse first when completely dead. if thats ok, open up and check the on off switch contacts are still ok as they tend to bend or snap off over time. anything inside that needs changing will need soldering..

if it's not the switch check the resistance of the elements wiring if u have or know how to use a multimetre. 0 resistance between the two thin wires means its ok. 1, infinite resistance, means the wire has burnt out and element needs replacing. its then cheaper to buy a new hairdrier as not all things are cost effective enough to save..

does the heating element through tunnel have a red glow? if so it will be the fan needs replacing. if no glow it could simply be the plug fuse. fans are always first to go because of moving parts, then the element due to heat build up, especially when fan breaks down!!

i re-checked all connections for bad earth, no luck. found a response that said change date as i was stuck on searching in 1st january 1970. went to settings, general, time and date. double clicked on blue date and had to scroll all the way down to 2014 and couldnt find a way to change year. once set to the current date, save and press top button till switch off shows and slide off. swich back on and signal should show pretty quickly. if intermittent serching then bad connection or bust blue inductor coil which is common, so much so u can buy them on ebay.
