Xv700 electronics & Electrical issue Using Jump Pack

PostAuthor: ironhorsecustomz » Sat Apr 21, 2018 3:35 pm

Ok so my 85 xv700 was running great then loss of power and I noticed it seemed to drop my rear cylinder so I check spark and it is only getting spark sometimes I have new coils new stator new CDI need to install them though but before I do I want to get a new pickup coil so that everything is new....I can't for the life of me find a pickup coil for a 85 xv700 anywhere I look does anyone know where I can find one or if one from another xv or xj model will work.

Mod Edit:

The OP is using a portable jump starter as a battery replacement, read on.

Has anyone ever tried to save money by ordering an aftermarket TCI from caltric stators and more? They list the TCI's for $78.00 my concern is that usually in life you get what you pay for.But I was wondering if anybody has tried one since used ones range from 80 on up and if it can be repaired the cost is 125 on up.

I have not tried them myself, don't remember any posts about them, but I don't see them all.

you might try looking through the vendor review forum ---> viewforum.php?f=30 there could be something there.

Yea..Much like Mark.. I've never tried "any" Catric things. Never seen "any" posts either. All I know of em, they're cheap and that says bunches. Only cheap things I get are usually from Harbor Frieght..when I don't have to rely on them. Specially something that could leave ya stranded in the middle of the desert. :bg:

1985 is Gen-II, but anyhoo... is there a bike salvage nearby? maybe OKC?

you'll have to get an "experienced" unit --- don't think anyone makes new/after-market.
https://www.mrcycles.com/oemparts/a/yam ... /generator

after '85 they changed the 2-coil-pick-up to a single, but '81 to '85 should work.

altering [2] singles into a double --- :con: ... electricity is magic to me.

know a good EE?

You mentioned in another thread, that you plan on buying a C5. If that is your goal and you suspect the TCI and/or pickups, why not just bite the bullet and buy a C5 ?

With the C5, you won’t need either TCI or pickups.

Re: Xv700 electronics & Electrical issue Using Jump Pack

PostAuthor: Jake » Wed May 02, 2018 6:51 am

I merged two of your threads together, they are closely related and involve the same issue.

I've never heard of anyone using a jump starter to replace the battery and that may be part of your problem. The Virago needs every bit of juice it can get and I doubt the jump pack is up to the job of keeping everything supplied. The jump starter is not meant for long term high current draw.

Add in the fact that it takes 3 hours to fully charge from a car cigarette lighter and that assumes no power is being drawn from the pack, with a little over a 7AH rating doesn't sound good to me. You may also be damaging your R/R.

Such device could be used on bikes that have magnetos, and kick starters, but I don't think it's viable for a Virago.

Others may have different opinions and that what this forum is about, so hopefully they will contribute.

Here's the link to the jump starter https://no.co/gb150

Sounds like hokum to me. More of something to keep in yer trunk or saddlebag. Or for those "Oh Crap" moments. Not for yer main source of juice. $375 buys alotta batteries. :;:

You are recharging the jump start at 5A ( NOCO specs from a cigarette lighter socket or auto power port ), odds are, you are consuming faster than you are recharging. Once your voltage drops below a certain point is when you start to have ignition problems. I'm not certain but I've read that the TCI requires 10V.

Keep in mind, this thing is only for charging the capacitor and is only meant to recharge and power mainly USB devices

Since the R/R isn't needed very much to charge the battery, all of the excess voltage is shunted off in the form of heat. I would wager your R/R will catch fire or at least fail when you're least expecting it.

I would suggest you switch to, at the very least, a conventional battery to see if your problems persist. The price of that thing would buy you a decent Lithium battery.

Actually I bought what looks like an oil tank but it's a fuse box since my rides never include to many stops I use the jump pak just to start the bike then throw it in my saddle bags the capacitor is just to keep everything going once it's started in retrospect it was a dumb and foolish move and should have just paid out another 200 for the c5 ignition that I want but live and learn

Re: Xv700 electronics & Electrical issue Using Jump Pack

Purchased my 1984 XV-700 new, in the crate in Nov of 1983. Sole owner with only 28,000 miles on it. Show room condition.
Used up the last of my OEM TCI units I purchased back in 86. The one that is on it now is the
OEM Mitsubishi unit that runs perfectly in starting, no tach bounce or faltering of any kind.
As I am on my last TCI module, I wanted to have a spare tci on hand. Ordered one of those $78 dollar aftermarkets
on line just to try out. Here are my first hand findings and observations:

A; Hard starting: Kicks back on the starter at random then fires only on one cylinder until throttle applied.
B: The tach bounces from 500 to 1,500 at dead idle. It does seem to run through the RPM range with no issue.
C: This square box has no mounting flanges or hardware at all. Just a black square box filled with black silicone rubber.
D: The male blade pins are thinner and narrower than OEM's and fit very loose into the TCI connector sockets. Not Good!

If your bike is completely dead, you may wish to risk it... Other-wise....Save your money!

I am currently completely re-mapping the entire TCI PCB with a thicker, full top and bottom annualis /vias with 2 side
heavy weight copper traces. This re-mapped PCB will be designed with one thing in mind: EASE OF REPAIR! These fail.
A good design will incorporate easy to replace and available components to keep these machines running another 50 years.
Hope this helps out or at least will save you some of your hard earned money.
Good luck out there.........
