Question about 1985 Honda CX 500 B

2 Answers

Rectifier Problem?? When the bike is very hot and I make a quick stop for gas, when I hit the starter button to start it up, it sounds momentarily like it's going to start then it feels as if the battery is dead, nothing, I quickly release the starter button, hit it again and the bike kicks over. I checked the battery cables, all good, recharged the battery, full charge.. This only happens when bike has been running for a while. On a cold start it starts up every time. Never a problem or symptom. Could this be a rectifier problem? Any suggestions?

    I have 1984 XT600 have replaced the statar,CDI,coil. The bike runs for a ;little while then stops dead, will start again after a couple of kicks, the will go for 10 mins then stop again. The only thing not replaced is the voltage regulator rectifier, could this cause the problem?

If the battery is charged, its charged..... redpoint5 is right, check the battery when hot... If the battery was not charging i would then look into the charging system, rectifier, etc.... Is it an air cooled engine? Sometimes engines can get a little warped when hot... My grandfather had Corvair vans as taxis that somehow always got overheated, after that they would never start hot. So, he had to leave them running all day.... If your battery is OK you may want to have a look at your starter.... Or, bypass the selenoid with a jumper cable and see if the starter kicks over fine when jumped directly...... That would indicate a bad or worn selenoid.

No kidding, try changing/adding oil. I have had similar problems when my cx500 and gl1100 are hot and the oils low--it's thin, slips down fast and just tough to start when holding in clutch lever. If I put it in neutral, it'll start up MUCH easier since the clutch is disengaged all the way. but still the oil is low when the clutch misbehaves like this.

bypass the starter solenoid crossing the 2 bolts, does this turn the starter motor?

Alright so about 4 days ago, I started my bike ( started slightly slower than usualy but started none the less ) Then I stopped to get gas, but when i went to start my bike again all I was able to muster...


This problem is the alternator is not charging. You will need to trouble shoot the stator, rectifier/regulator. You will need a volt/ohm meter. It is best to get you a good manual. But as always check your fuses. The stator will produce AC voltage in about the 27 - 32 volts AC range at idle. Unplug the stator and check for voltage there at this plug when idling. Next plug the rectifier back in and check for voltage at the battery at idle, should be in the 14 volts DC range. If you are getting the proper AC voltage at the two wires on the stator and only battery voltage at the battery, then your rec/reg is not doing its thing. Hope this helps FixYa up.

Electric starter will not switch off, unsure why


Sounds like you had to disconnect the battery to stop the starter from spinning.
I've had that happen quite a few times and heres what i found and did to fix the problems.

1. I had an old american bike in the shop with a low battery. I didn't know the battery was
low when i hit the start button. The starter solenoid stayed engaged, and the starter kept
turning over the motor, I pulled the battery terminal off to stop the power to starter.

I check battery and it was low, i put full charge on trickle charge and then let it sit
a 1/2 hour before i tested it with the load tester.
It failed big time, dropped all the way to bottom of the scale under a load test

Installed a new battery and fixed the problem. The solenoid, start button, kill switch, key switch all works, it was just a low battery.

2. I had a customer call me because he ran out of gas, when he got gas he turned the bike over for a long time trying to fill the carburetors with gas,
Never hold the start button down for long periods of time. He did and the wires got so hot that the positive wire from the battery to the solenoid melted and stayed engaged.

It was an easy fix, replace the melted solenoid, and only hold the start button in 5 second intervals, allowing it to cool in between starts.
Once the bowls were full again and the bike starts, then it only takes about a second for the bike to start so you normally dont hold the start button for that long.

Hope this helps

New battery in bike, good spark,plenty of fuel.When I hit start button bike makes attempt to start but dies(sounds like not enough juice in battery) to turn bike over.With headlight on dosent dim mutch...


hi, that still sounds like a battery problem, however, when does the spark come from the motor when you press the button? this could be the insulation inside the starter breaking down alowing it to go to earth when the button is presed,or simply a poor conection, when you remove the nut from the starter hold tight onto the cable with some grips this will stop the bolt from turning inside, failure to do this may cause the wire inside the motor to break, and or earth out, remove the nut, cable then note the order of the washers fibre and metal, on the shank of the bolt you should see a fibre washer in the hole around the starter check this is in place, clean up all surfaces including the eylet on the starter cable with some sandpaper reasemble and recheck

Could the R regulator cause my firestorm to keep cutting out ?


Regulator will stop the bike starting often and will cause the dash to go blank when you hit starter button. If you do manage to start the bike by bump starting it and run it eg; to get home after this happens you may cook the battery or do damage to the stator. You need to check these three things as there all linked and effect each others efficiency. Excess charge on electrical system is converted to Heat by regulator rectifier unit so in effect the battery cannot be overcharged.

Engine cuts out sporadically when driving and wont turnover when trying to start for a few minutes after. When starting if clicking noise comes from the rectifiers the bike will start if no click bike wont...


It sounds like the starter solenoid (you said rectifier clicking) may have burnt contacts. If you jump the solenoid with a piece of wire (touch the wire coming from the battery to the wire going to the starter ) and the starter works, it's a bad solenoid. If you hold the starter button and gently tap on the starter with a plastic hammer and the starter works, you need to replace the starter brushes.

Wiring


Lets start with the battery. There should be a relay of some kind with two large wires hooked to it, and maybe 5 other smaller wires. Now the one large wire should go to the relay direct from the battery, then the other large wire will go to the starter. When the connection is made between these two large wires the starter should turn. Now there will be one or two smaller wires that control the relay, ( these are hooked to a post or posts on that same start relay), so it will pull in and make the connection between the two large wires to turn the starter. You can check this with an old school 12v test light, hook a hot wire to one side of the start button from a hot wire here in the relay, (one that is hot when the clutch is pulled in or the bike is in neutral -- clear as mud?) or it can be hot all the time, but the starter will turn every time it's touched. Some old school bikes are wired like that anyway. Go and push the starter button and check wires until you find one that gets hot only when you push the start button. Then back to the relay, pull that hot wire from the start button to the relay and touch it to the small post and see if it will now energize the relay when the start button is pushed. Now once all this wiring is fixed it should turn over the engine, when the start button is pushed and it's in neutral or the clutch is pulled in or it will take off on it's on. Next the Alternator, one of the medium sized wires should come straight from the battery to the regulator nothing in between, thats is the regulator exciter wire, next is the, alternator wires, there should be 2 or maybe 4 wires coming out, and if there are 4 they are in pairs these are the A/C output of the alt. These wires will hook to the rectifier, You should have one wire going to ground from the rectifier, then, these 2 wires from the alt. then a wire that hooks to the regulator as 12v hot out of the rectifier. See this is how the Alternator works is produces A/C voltage (say 28, 30 volts A/c) then the rectifier converts it to 12 volts + - D/c the - negative is the ground wire. The regulator will Check the volts at the battery and adjust the output of the 12vdc from the rectifier and let it pass on to the battery to charge it. I hope some of this helps you, I hope it makes sense. I would love a bike like this. . . .

Bike will not crank


it's not the starter or rectifier for sure! check start switch, clutch switch, and kickstand switch. if all are good then check fuses and wiring.
