AI Thread Summary
The discussion centers around repairing a fried speed controller on a 900-watt electric scooter with three 12-volt batteries. The user is seeking advice on bypassing the speed controller using a high current relay to increase speed, while also expressing limitations on upgrading components. Respondents caution against bypassing safety features like the speed controller due to potential dangers and liability issues. Suggestions lean towards repairing the existing controller instead of attempting a bypass. Overall, safety and proper repair methods are emphasized over modifications that could lead to instability.

ok guys and gals here is the deal...i have managed to get my hands on an electric scooter that has the speed controller fried...now it has 3 12 volt batteries hasnt been charged in about 9 months. it is a 900 watt scooter and I am looking into repairing this and making it go as FAST as possible...

now here is the thing...i heard you can bypass the speed controller with a high current relay or something like that...how do i bypass this and what do i need? anyone give me any direction? there is also the more batteries bigger motor thing but i can't do that...im trying to work with what i have...if anyone can give me any direction as to what to do i would be so greatful thank you very much

To be honest mate it sounds quite dangerous what your doing. By-passing manufacturer placed things like speed controllers is not advisable and anyone who could tell you how to do it will be worried about being liable if they give you any advice. I'd find something a bit more simple if I were you, there's loads of other interesting avenues out there :wink:
 
i need to know more about this does anyone know?
 
Not enough information.
Without a controler to ramp up the power it is likely to just flip over.
I would look into repairing the fried controller.
 

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Question about bonding ground and neutral'

I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
