another "what's this?"

Post by winguyjo »



the single wire on the right is the ground for the neutral switch. no problem there, can put it anywhere, just wondering where it would normally have been mounted ?
the frayed loom on the left houses two green "plaid" wires ... the conductor looks like aluminum. doesn't look like anything honda would do. it disappears under the front of the engine. any thoughts on that one ?

thanks
joe

The single wire with the eyelet is the neutral switch wire, has to go on the neutral switch on the lower right of the engine. The others kind of look like the fan switch wires.

hi, dave, and thanks for the feedback.

that single (neutral ground) wire seems to originate from under the engine. i checked on my '82 and it runs up behind the timing cover and disappears somewhere around the top/middle of the engine.
i will just find an alternate place to ground it (although i am a bit anal about keeping things the way they were; thus the question ... but it would be silly of me to remove all the stuff necessary in order to find out where it goes to).
the 2 green plaid wires are definitely not fan-related as the factory wiring for that is in place, connected, and functioning. they also originate somewhere under the front/middle of the engine which makes me think they are factory but the color and the conductor material make me think "add-on". regardless, the bike runs without them connected to anything so i guess i'll cap them off and tuck them away until i discover that something isn't working (the fairing is removed, for now, so could be for a volt meter or something).

UPDATE ...

it seems i was mistaken as to how the neutral switch/light works . the neutral light is ALWAYS on when that single wire is grounded ... thus giving a "false" neutral.
i found this out the scary way while crouched down checking for voltage drop at the starter motor; hit the start switch and the bike lurched forward a bit. :shock:

so ... i need to figure out where to attach that wire.

on an unrelated topic ... i noticed that the rad always wanted to push coolant up into the overflow tank while running. not a huge amount, just a drop at a time, but that didn't seem right to me considering that i had the rad, and overflow tank, properly filled. then i noticed that the rad cap was marked "7 lbs". i smelled a rat and went checking the parts list. i come up with rad caps for these bikes being rated at 0.9 atmospheres ... a few strokes on the calculator shows me that i need a rad cap rated for 13.5 (13?) lbs . can someone confirm this ?

thanks

That's why that wire is supposed to be connected to the neutral switch, as I stated above.
Yes you are correct on the radiator cap.

once again, thanks for the help dave.
yeah, i kinda glossed over that part about it going to the neutral switch because by grounding it i was getting a neutral light and it was just lucky (or unlucky) that the bike happened to be in neutral so i figured all was well.
can you please clarify the location of the neutral switch ? i know you said bottom right, but is there something i have to remove to get at it, because it's not jumping out at me.

thanks

o.k. ... a bit of searching shows me that the neutral switch is inside the front cover.
am i correct then in thinking that the front cover has to come off and this wire somehow attaches directly to it ?
if so ... thanks a lot PO . :(

EDIT : further searching reveals that on '80 and '81 the neutral switch is not located under the front cover ... whew ! it seems it is located somewhere under the right side cylinder head, conveniently obstructed by the frame. will go out tomorrow morning and hunt for it, but it can't be nearly as bad as removing the front cover ... can it ?

Well, it ain't easy. You can see it but getting to it is another thing.

well, the plot thickens ...
no neutral switch on the side of the engine (no kidding about it being difficult to access even if it were), which means that it's under the front cover, which means that this engine is either an '82 or '83, which means that i had the idle air screws 1 1/2 turns out of whack, which explains why my idle wasn't too good (it's much better now that i turned it out another full turn).
good times !

The wires come out the top of the front cover then behind the right timing cover if it is an 82 or 83. 83i has 2 wires, 1 for neutral and 1 for OD, an 83 aspencade engine has 6.
