Halogen Headlamp Conversion and Brake Seal Lube
Trigger:
I am shite with electrics and have a problem with a 750 that drains the battery when the head light is on. The Halogen bulb is 60/55 and i thought that this was the problem but, to throw a spanner in the works, Julie's 550 has the same headlight and bulb, with a smaller battery and has no problems.

My 400 is using a halogen 60/40w headlight bulb without any problems at all.
The original bulb was 50/40w so dipped beam is still the same at 40w. I hardly ever need to use the full beam but it's not a problem when I do.
No relay used. I have a Motobatt battery which has a bigger capacity than the original spec which probably helps.

You can separate the charging out from demand to give you more insight.
With it switched off and not recently run, put voltmeter across battery and it should be between 12.5 and 12.9 volts for healthy battery.
Start it and let it run with no lights on, then it should rise to peak of 13.95 volts and stop at that when you rev it to 3000rpm which is healthy charge rate. If it doesn't get that you've something wrong with charge circuit.
Edit:- Honda manual for 750 gives max voltage as 14.5 when at 4000rpm then not exceeding that for any higher revs.
If that all checks out then you're more likely looking at demand that's draining it.
Compare the checks on this one to Julie's 550 to give comparison and quick cross check.

Went through the whole thing with Hairy via PM last year and could not come up with anything. It will be stripped at the weekend and will investigate the loom as, it is the only part not changed .

Any help or suggestions would be gratefully received.
Many Thanks

Honda manual for 750 states "coat the piston with silicon grease and install it" also "Apply silicon grease to brake pad outer circumference and install "
"WARNING braking performance will decrease if silicon grease is applied to the pads/disc contact surfaces" is stated at the end of above section.
