Dyna S causes 3V drop at coils?

[posplayr]

Yeah that's the one I came across earlier. Thanks for the detailed right up.

I was pretty irritated that new coils made it run worse . But it's all starting to make sense now! I'm so sick off looking at black plugs and scratching my head.

I would recommend if at all possible:

a.) to open up the harness and solder the connection at the "T" between R/R(+) and Battery(+) to improve your charging; This is at the back of the harness.


b.) to open up the harness at the coil split (O/W) to reduce the coil Voltage drop. (else wire direct to the coils from the relay)

c.) clean your fuse box and flow some solder into the old crimp style fuze boxes

I will do all these things. Thanks. You don't mean solder the glass fuses in do you?

While I'm at it is there something else I should be looking for that could cause the 1 volt drop between the battery and coils when I directly wired them? Or should I do the relay mod and clean up everything else and sort the charging system first and go from there? The coils were still wired to the existing O/W wire at the time.

Cheers.

I would do it all at once. It is not that complicated. Review the changes in the GS Charging system health which covers primary grounding. The extra things mentioned are primarily in the harness and fuse box.

No don't solder the glass fuses. If your fuse box is not crimp style in the back good just clean it and use dielectric grease..

Will do. Just been to the auto parts store & loaded up with goodies, including a whole lot of spade connectors and heat shrink; reckon it's time for the old bullets to go too.

Well I wouldn't have believed it if i hadn't seen it. Did the coil relay mod and now only 0.1 volt drop between battery and coils. This is awesome . I've read about it heaps on here but was always slightly daunted by it. Wish I'd done it two years ago.

Now onto the charging system. Fully charged battery has resting voltage of 12.8 V. RR putting out 14 volts at 2500rpm and over 13 at idle so now I just gotta get that to the battery. SWEET!!!!


Thanks heaps for pointing out what I was refusing to see.

Glad it is working out
