Tommy xs Posted October 2, 2013 Share Posted October 2, 2013 sound's like you have a bad earth connection you'll need to clean all your connection's and make sure there tight Link to comment Share on other sites More sharing options...
Moderator Airhead Posted October 2, 2013 Moderator Share Posted October 2, 2013 maybe a bad ignition switch though, to prove that fit a jumper from battery+ to one of the brown wires Link to comment Share on other sites More sharing options...

If youre that much of a novice you better make the jumper fused, say 20A...or get someone to do it for you because frankly if you did actually do what you were thinking of (which isnt what I suggested) it would be a fire risk Link to comment Share on other sites More sharing options...

slice Posted October 3, 2013 Share Posted October 3, 2013 You have a short circuit then, that's why the battery is going flat, disconnect the indicators and lights (remove fuse) and see what happens? Link to comment Share on other sites More sharing options...
blackhat250 Posted October 3, 2013 Share Posted October 3, 2013 Put a meter on the battery when engine"s running , should be 14.5 volts . to see if you have a regulator and charging issues. [ thats if its a 12 volt system] Link to comment Share on other sites More sharing options...
mcnamara1710 Posted October 3, 2013 Author Share Posted October 3, 2013 Confused.com.i bought a 6v battery ehich i was told is the one for my bike.but there was a 12v on the bike when i bought it.checked bulbs they day 6v Link to comment Share on other sites More sharing options...
mcnamara1710 Posted October 3, 2013 Author Share Posted October 3, 2013 What should i do if it is 6v.the same and if so what should it read thanks Link to comment Share on other sites More sharing options...
slice Posted October 3, 2013 Share Posted October 3, 2013 You say you took OFF a 12V battery but the bulbs are 6V and then you put back on a 6V battery? Not sure where you are with this, one of the guys on here will come up with a reg/rec reading to help you out. 12v system should be as stated 14.5V or there abouts, but you need to find out what it is actually putting out before you do anything else. Put a meter across the battery neg - pos terminals when it's running and see what it reads. I do remember someone saying that to convert your bike to 12V you could use a TZR125 generator, maybe that has been done to your bike? Cos it originally was a 6V system when it was new and some folks hated the lights (or lack of) on the bike. Link to comment Share on other sites More sharing options...
blackhat250 Posted October 3, 2013 Share Posted October 3, 2013 just checked , the RSX100 is 6 volt,,, lets get the correct battery , and go from there,, Link to comment Share on other sites More sharing options...
mcnamara1710 Posted October 4, 2013 Author Share Posted October 4, 2013 Hi blackhat,I've taken the 12v off now and replaced it with the new 6v i bought a week ago.yes 6v is not very good at all very dim everything on bike now.just don't understand how the bulbs didn't blow with a 12v on it if it is a 12v.spoke to the guy i bought if off.he said he has never touched anything on it and he has had it 7 months.he bought it from original owner from new in 1991 Link to comment Share on other sites More sharing options...
dt502001 Posted October 4, 2013 Share Posted October 4, 2013 Hi blackhat,I've taken the 12v off now and replaced it with the new 6v i bought a week ago.yes 6v is not very good at all very dim everything on bike now.just don't understand how the bulbs didn't blow with a 12v on it if it is a 12v.spoke to the guy i bought if off.he said he has never touched anything on it and he has had it 7 months.he bought it from original owner from new in 1991 First thing you need to do is determin what the charging system is putting out,it may very well have been converted to 12v and if your running a 6v battery your running a risk of it blowing up form being over charged. Get a multy meter and connect it to the battery with the bike running if it is making 12+ volts then shut the bike off immidatly and get a 12 v battery before you get hurt.

Speedshop Posted October 4, 2013 Share Posted October 4, 2013 This wiring diagram will solve all your problems, study it carefully - it works on most Yamahas and is the the same with 6 or 12 volts. Link to comment Share on other sites More sharing options...
