Auto-electrician suggestions, Auckland?

[tonci]

Hi Guys,

I am currently having intermittent electrical issues with my motorcycle and am unsure of a good auto-electrician to use.

My bike is a 1972 Honda CB500Four, I am unsure of the cause of fault but it has total power loss at stages or seems to have very low power at others.

Any people with experience on the older bikes would be a bonus.

I am in the Auckland area, Western Springs to be particular so as close to there as possible would be a bonus.


Thanks in advance

when you say "very low power" you mean electrical power, or engine power?

if electrical, you've probably got an old wire rubbed through and going to ground. unhook the neg. terminal of the battery and put a testlight/ multimeter between the terminal and the wire you just took off, if it shows voltage this is your problem.

otherwise basic starting/charging system check (battery standby volts, running/charging volts) which will determine what you have to replace.

if you mean engine power then it's another kettle of fish...

Hi,

I personally don't have the knowledge or experience to work on this myself, and although I would like to learn think it would be better to have a professional work on it for me.

In terms of what I meant by "very low power" I meant electrical power, at this stage my bikes not starting because of the electrical issues.


Thanks.

If you have had anything apart (especially the seat off) take it off again & check you have not pinched a wire or jammed it against the frame as this will account for your symptoms.

i have a mate in waitakere who could look it over, or if you could wait until mid next-week i'll be coming down and could give it a once-over. from the sounds of it your battery is poked/undercharged, it's just a matter of WHY that's the case. have you got money for a new battery if required?

With admitting ... you have neither knowledge or experience ... how are you sure it is electrical ... ???

However ... On a 1972 550 four it is likely there are several issues involved. As well as electrical ...it is likely to have low compression, which is known to reduce the ability to allow good starting/running.

Considering the fact that the motorcycle has no power going to the headlights, tail lights and dash lights, the horn doesnt operate i would be hazarding at it being an electrical fault as the cause.

I will hopefully get the chance to replace the battery during the week, and will see if this makes any difference, but i think that although the battery is a wee bit tired the main fault lies elsewhere.

I am wondering if it would be worthwhile having an auto electrician replace the entire loom and fusebox with new ones.

highly unlikely. that will cost a stack.
you can replace fuses yourself, although i'd probably go find a handy-man neighbor with a multimeter to continuity-check them all first. also get said handy-guy to hook up the bike with jumper leads to a running car then test the electric systems.

as said, i'll be in akl mid-end of the week and can have a geez at it. PM or 0224 637 583 if you're interested.

if you're really serious about spending money contact george at the motorbike doctors (mobile mechanic) he'll come to you. i have several mates in auckland who use him and frankly, can't shut up about him. (they're well paid executive types. i don't know how much he charges)

Hey Akzle thanks for the offer, I might contact George and get an idea about costings, otherwise your offer is very generous. Thank you, will PM or message you if required
