Why not wire it so you dont need the micro switch?? It can be done. If you want to know how just email me and I will show you how.

All you have to do is disconnect the wire that goes from the top end of the resistor to the full throttle contact tab.  Then run the one wire from the relay to the wiper arm and the other to the full throttle contact tab.

Re: Adding a relay for around $10.00

One reason i can think of, th nice flexable wire to hold up to long term use on teh wiper is not readily available to everyone.  The Micro keeps all wiring to the handle and has almost no wearable parts, or wire routing for contact ware inside the top.

Re: Adding a relay for around $10.00

Ok it may be a dumb question, is the relay a 12v relay? Does a 9v battery have enuff to operate it? Or do you need a 6v relay so the 9v is plenty of voltage to run it? I understand eletrical switches can use up to the voltage and amps they are rated at but are relays the same way?

CA the relay is a out of a car (Ford) 12 volt relay. And yes the 9 volt battery is enough to operate it.

Re: Adding a relay for around $10.00

Okay thanks DVAN thats good to know,I found some 6v ones new they were almost 30 bucks each! Ive got plenty of 12v ones laying around.

Both my 12V relays been working fine on a 9V for well over a year now.

HK could you post your pic on how to set up like you say, thanks.

All you need to do to by pass the micro take the wires from the micro and run one of the wires to the wiper arm and the other to the full contact point then disconnect the white wire coming from the resistor to the full throttle contact.

I have a picture on Photobucket, how do you make it show up on this board???????????

Re: Adding a relay for around $10.00

Does anyone know of a relay switch that you can use a 9 volt battery to activate and will handle 200-300 amps?
I have seen those rather large boxes with 8 ga. wire and clamps. I would like to build one. The 30 amp ones do not hold up to the amp draw of the high power high torque motors.

Thanks,

Russ

Re: Adding a relay for around $10.00

I am using a 40 amp one for my NEO motor I got it at advanced auto parts and a 9v trips it fine

Re: Adding a relay for around $10.00

I build my own control along time ago since the difalco had problems.
I used a turbo frame and made an alum bracket ,ferret reostat and small push button , miroswitch mounted to the frame and to bosh relays in parallel. The reostat controls the rollout speed and is activted by the push button. I mounted the repays in a box about 7 inches from the clips, the micro switch activates the relays. It has worked great, mind you at that time the fastest stuff I had was quad 20 cars running mid to low 7s

Re: Adding a relay for around $10.00

I have a Koford KM558D controller. Can I add the relay without the 1 ohm wet wound resistor?
Also instead of using the micro switch, can the trigger for the relay be placed on the last wiper. I believe in the model I have, there is a yellow wire running from the contact to the white wire. I can remove it and add the contact wire in its place. I have a 70AMP relay, terminals and socket plus all kinds of 10-12 gauge (UL1015) wire available. Only thing I would have to purchase would be a 9v  battery and the adapter, unless I steal one from one of the grandkids toys...lol


It is not always possible to be the best, but it is always possible to improve your own performance.
