Electrical help for my T500
I've already learned so much just by looking at the posts on here! Allan's tips for cleaning up old harnesses is great, inspired me to start looking at what I need to do. First issue is this...
Is this just a matter of splicing on a new spark plug cap wire or does the coil get replaced? Is there a life expectancy to these things? Can I replace one coil and not the other or do they both get replaced? I saw someone on here has been using one for a Harley... are they that interchangeable?
Second issue. I picked up one of those small Ballistic Evo batteries. Do I need a new rectifier if I'm using this newer battery? I was looking at one of these http://www.ebay.com/itm/TRIUMPH-BSA-NOR ... 50&vxp=mtr" onclick="window.open(this.href);return false;" onclick="window.open(this.href);return false;" onclick="window.open(this.href);return false;
And lastly, the PO didn't have a key for this bike so he cut off the contact box and twisted the wires together. Is there any hope of my finding a contact box to connect to the new ignition I bought for this project? I was looking through microfiche and couldn't find a part or number. Any help would be mightily appreciated (on top of the help you've already given without knowing it )
Cheers!

Re: Electrical help for my T500
If the HT wire is still long enough, then trim a little off the end so you have a good electrical connection to the new spark plug caps.
NGK has resistor & non-resistor spark plug caps. Get resistor caps if you are using non-resistor plugs, and get non-resistor caps if you are using resistor plugs.
You need to upgrade to a modern rectifier/regulator when using the Ballistic Evo battery.
The Tympanium rectifier/regulator in your eBay link is what I have on my T500.
For info on how I installed it see: viewtopic.php?f=2&t=4858&p=109480&hilit ... um#p109480
What do you mean by "contact box"?
If you are referring to the ignition switch assembly, some are still available from Suzuki. eBay is another option.
Also, you can get replacement keys via eBay.

Re: Electrical help for my T500
By contact box I mean the connector from the harness that connects to the ignition switch. The little white plastic part. He cut it right off and wrapped the wires together in a bundle.

Re: Electrical help for my T500
You could probably replace it with a 4 connector latching (or non-latching) connector from this place: Vintage Connections

Re: Electrical help for my T500
Thanks Conner, but your link brought me here: http://www.myspace.com/video/steve/mors ... ng/8542413" onclick="window.open(this.href);return false;
But I know what you were getting at
If I'm using the new rectifier and still attempting to use points, do I need to change any of the wire gauges? I wish I knew as much
about electricity as I do about nuts and bolts. And that's not a lot.

Re: Electrical help for my T500
Oops... That was the link I pasted in the Facebook page thread.
Vintage Connections
No need to change any wire gauges. The new rectifier/regulator setups actually limit the peak high voltage, which is what boils the electrolyte in lead/acid batteries, and damages AGM batteries.

Re: Electrical help for my T500
The cap that's on there now is a NGK LB05E, I'll look up to get a match for it. Didn't know it was so easy to swap those out!

Re: Electrical help for my T500
Put a pair of these on my bike last summer. Keeping with the factory (non-resistor) spark plugs, you use the resistor cap.

Re: Electrical help for my T500
So what's the difference between the LB05F and the LB05E? Is it a fitment thing? I've also seen an LB05EZ and LB05EP and others... It's all Greek to me...

Re: Electrical help for my T500
I believe it is whether the cap attached to the spark plug with the screw-on terminal in place, or with it removed from the spark plug (for the LB05F, you remove the screw-on terminal).

Re: Electrical help for my T500
What did we ever do before the internet?
Thanks Conner... that's awesome. I've learned a lot tonight!
I'll go with the E and leave the tips on the plugs just to keep it consistent. Have to imagine that the Fs would stay
attached better but I guess I'll find out!

Re: Electrical help for my T500
By the way, here's what the PO left me with...
which is supposed to attach to my new ignition here...
And what could possibly go wrong with this?
It looked better before I took off all the electrical tape holding it in place.
And I think I can now get rid of these...
Now that I have one of these...
Now to figure out what's the difference between a negative ground connection and a positive ground connection.

Re: Electrical help for my T500
Ugly but not uncommon.
You are correct. Remove both the stock rectifier & voltage regulator.
First look at the stock wiring diagram & figure out what each wire is.
Three copies (one color & two B&W) of the wiring diagram are here: http://www.ozebook.com/compendium/t500_ ... 00wire.jpg
Wire the Tympanium up the same as I did. Black goes to ground.
For my install pic & wiring diagram see:
viewtopic.php?f=2&t=4858&p=109480&hilit ... um#p109480
To mount it the way I did:
1) one of the bolts attaching the battery box will need to be replaced with a shorter bolt
2) the shorter bolt needs to be turned to give maximum room for the rectifier/regulator
3) use a file to slightly increase the width of the slot for the other battery box bolt
Make sure to clean up those connectors & replace that ugly fuse holder.

Re: Electrical help for my T500
You soldered the 3 'Y' connectors instead of using a dual or triple socket terminal? Did you just wrap them in tape?
I'll have to sit down with my own harness and this diagram of yours and try to get everything figured out and marked.
Oddly enough it sounds like a fun project! Looking to get a new fuse holder, local dealer has them for $7.48. I should
stop making a bunch of small orders and just go through the whole thing and make one big order!
Cheers!

Re: Electrical help for my T500
My "Y" connections are something like what Suzuki used to do. But definitely not up to the impressive standards of Suzsmokeyallan's work.
I trim the insulation off of the "main" wire where the junction will be.
Then attach the other wire & solder them together. Trim any wire stands that stick out.
Cover the junction with something like heat shrink tubing.
Finally wrap the wires together with electrical tape to make a little wiring harness.
Don't make a "T" connection -- flexing could cause the joint to fail.
The wiring harness prevents flexing of the solder joint, which could cause it to fail.
Have fun.
