1981 Honda C70 Passport (04) - Testing the electrics

[@iadamr2429]

hi just a little tip for you you can take off the seat and then after taking off the seat you'll see the gas tank and once you take the gas tank off it's just a couple of screws and then you see the negative Slide the battery through there and it's a lot easier to connect the wires for me. but I am working on the same bike you are

[@TheMightyGarage]

+Adam Smith Hi Adam, thanks very much for the tip. Much appreciated. Cheers!

[@rallenfontenot2978]

Mi Ty thanks for all your Passport videos! I have watched them several times over. I am looking to buy one and you have been very helpful!

[@TheMightyGarage]

Thank you very much Rallen. Good luck with yours. Best wishes, Mike

It think my family tossed my old battery which I think had the negative part attached to it 😵‍💫 wonder where I can find the negative part😖also do we need to have the clear tubing on the battery?

Question I have a 1981 c70 turning light remain firm instead of blinking is this do to low battery life?

[@roccob9011]

Hello, I have a question regarding the wiring. I tried to it on yoru video but not saw it clearly. I have one black wire with white stripe 18 ga in the battery compartment and i have noi idea where it goes. Could you help?

Good video .

[@nadarajahkulanthaiappan7163]

My Honda C70 1984 has a problem , hope you could answer . When ignition switch ON , neutral light , signal light ( left / right ) not working but when engine started , neutral light brightens and signal lights working on the run . What could be the reason .

[@garnermiller1079]

Thanks for these, been so helpful w work on my ‘81. About the only thing you didn’t have issues with that I did was my flasher relay no longer blinked- simple repair- opened the relay and the metal contact had warped over the years so it no longer touched the contact when juiced up. Bent the contact a bit w pliers and good to go!

[@TheMightyGarage]

Thank you Garner! Glad it helped! Best wishes, Mike

I’m helping a friend rebuild one of these and his battery wires were corroded but I’m not very bright when it comes to electrics. What gauge should be used for this?

[@edwardoutthere3189]

Have red blue wire coming out beside battery on loom just there bared end cant find where r what's its purpose any idea everything seems t b working any ideas on red blue wire 1979 honda c90 6 volt

[@rymburt]

Hi. Thanks for posting these videos. They help al or as I have an 81 red c70 too. What was the secret to extracting the turn signal wires from the signal itself? I'm holding the signal and cable in hand but don't see how to remove the plate and spring.

[@TheMightyGarage]

Hi RB. Hope my email response helped. Cheers, Mike

[@rymburt]

It does. Thanks!

Location of ignition coil

[@ΔημήτρηςΧαραλάμπους-θ1γ]

how parking light work?

[@iadamr2429]

no problem I'm working on the same bike you are but the bike is for me and I am taking all the Chrome in pieces off so I can repaint it its original color so we're doing a full restauration on it it's been lots of fun I've also been wet sanding the bike.

[@TheMightyGarage]

+Adam Smith Wow, that sounds like a much more comprehensive job than I'm doing. This and another bike belong to a neighbor who asked if I would try to get the bikes running again. I'm happy to help out and have learned a lot.. especially that Honda electrics are significantly better than Lucas, which is what I'm used to ;) It's just a great bike. No wonder they have made millions!

[@viviandoyle2392]

Just got a 1981 Honda won’t start battery seems ok 6.5 v what’s my next step

[@rallenfontenot2978]

Mi Ty what kind of "battery tender" did you use? I have a 12 volt charger that can be used at 2 amps as a trickle charge. Would I be risking burning out bulbs being that the 1982 is a 6 volt? Thanks

[@TheMightyGarage]

Hi Rallen, I wouldn't recommend using a 12v charger on a 6v system. I use the Deltran trickle chargers but my friends use very inexpensive chargers and they seem to work just fine. Good luck!

[@rallenfontenot2978]

Thanks Mi Ty.

[@TheJoyriderDub]

I have an 82 usa model 12v and my headlights dim when the revs go down think its my rectifier? Any ideas lol

[@prezsztyber2319]

Link to battery by chance?

[@jeffwalsh6343]

Hi, can you tell me if theres a difference in legshields between a c70 and a plaggy as ive never heard the word "Plaggy" before but it seems to be related to the c90, theres a legshield for sale on Ebay described as a plaggy and im unsure if it will fit my c70 passport, my rewire starts today ;)

[@TheMightyGarage]

Hi Jeff, sorry but I don't know what the Plaggy reference is. It sounds like perhaps a particular model? I googled it and there were several references, so it may have been a model with some special features. Good luck with the rewiring! Cheers, Mike

[@rallenfontenot2978]

Mi Ty I have a question about my turn signals -please. Rear right works 90% of the time but occasionally will not but then it "fixes" itself. I've looked at the socket and it seems to be a bit tweaked as the bulb is not totally secured. If I want to change the entire turn signal assembly do I have to remove the brake light bracket etc to be able to change the turn signal out completely or can I splice it near the stem end. Thanks! After re watching I think I have my answer but I still hope to hear from you. Cheers

[@teddyanderson]

Neat

[@angeloshonda]

My ‘81 c70 passport’s horn and signal lights , tail lights and headlight aren’t working. Any idea? Fuse ??!! 🤔

[@TheMightyGarage]

Hi Angelo. Yes possibly a blown fuse, or maybe blown bulb(s) or a wiring problem. I assume that they were working before and other electrical components are working okay (i.e. the battery is good).

[@Omanivibes]

I still have same..

[@StephenFujiwara]

Great video, very neat and tidy little bike! Is this one 6 volt? Your battery looks to be twice the size of mine! (1977 C90)

[@dominiccannistra]

quick question if you still respond to this video, my 81 seems to have all the necessary lights working when the ignition switch is on, neutral light and twilight, but i was told headlight and signals work off the engine strator and you have to have the engine running to have them on, this doesn't seem to be the case with yours... i don't get any power to the wires that control the headlight but it shares the same ground system as the tail light and that works. is something wrong in my wiring?

[@TheMightyGarage]

Dominic Cannistra Hi Dominic, here is a response from one of my friends who is terrific with electrical issues.. I am not very familiar with the C70. It seems to me that about 1981/1982 they switched from 6 volt to 12 volt electrics. This probably means that they also switched from an alternator powered headlight (only lit while engine runs) to a battery powered headlight that can be lit without the engine running. Perhaps he just has the earlier version.... Hope this helps, cheers Mike

[@Bransonio]

This also has me puzzled. I don't believe it is typical for the 6v bike headlight to come on under battery power alone.

[@popptj]

Thanks for the video. Helpful! Non bike question: What kind of video camera are you using? Great quality video.

[@TheMightyGarage]

+popptj Hi there. I'm actually just using my iPhone! It's a basic 5S model. I have a little inexpensive tripod with a phone clamp attachment to hold everything nice & steady. For some of the longer videos and ride videos, I use a GoPro Hero with a GoPro "Chesty" harness. Again, it's just the basic model with the simple push button on the front. It will capture about 4-hours of video. Cheers.
