January 21, 20215 yr Hello all, i diaz from Indonesia. I have problem with my 2nd hand Montesa just i bought.. this Montesa come with Accu connected tO rectiffierregulator pin ignition for positive and extra ground cable as negative from accu.. i try tO disconnet the battrey but i don’t know the original cable conection for rectifier regulator. Would it be possible tO get some help from this form?
January 24, 20215 yr I don't' know of any 4RT's that use a battery... If it really is a 4RT and has one it has likely been modified. As such you will want to start looking into the electrical diagram of the bike and see if you can figure it out. Good luck. https://www.manualslib.com/manual/853548/Montesa-Cota-4rt-2005.html Edited January 24, 20215 yr by jonnyc21

January 26, 20215 yr The 4RT doesn't need a battery to run, it wasn't designed to run a battery by Honda and HRC This is probably the source of your non starting woes, if someone has fitted a battery? It doesn't need one, why did the previous owner think it did? Remove the stupid battery and return the 4RT to stock, set tickover at 1800 rpm and the bike will run and run Edited January 26, 20215 yr by johnnyboxer

I have never seen a 4RT that uses a battery, not my friends 2005, my 2007 or my 2017 or any of the others that I have had the chance to ride... maybe this is an Indonesia only configuration? If so I wouldn't have a diagram for that. The diagram here shows a condenser (capacitor) that in the case of the 4RT is used to buffer the system to work without a battery. This allows you to kick the bike over once to charge the system and then on the second kick it will start no battery needed. If the bike you have is running a battery I would consider checking the condenser/capacitor is good as it might be causing a fault to the system having been connected to a battery all the time when the system was not designed for that; unless it has a disconnect that is used every time the bike is not in use? Sorry I am not able to be of more help. Best of luck. Edited January 26, 20215 yr by jonnyc21

It will likely be several more weeks before I would be able to spare the time to take it down to the point I could take any pictures. However if you get a good copy of the diagram it has the color codes on it the legend is in the lower right of the image you posted. See the example snip-it to see a sub section decoded a bit using the legend. . Edited February 2, 20215 yr by jonnyc21
