Suzuki DT8 Outboard

rectifier circuit in jan2011 PBO with a correction on the fora to the size of the capacitors .
4700 instead of 4.7

but as the thread is 6/7 years old guess the dt8 will have worn out now !

Small outboards usually have a relatively low output charging coil. 5 or 6 amps max or something like that. They are not usually fitted with regulators.
Larger engines esp those with power tilt and trim systems are likely to have larger charging coils and then to have regulators, possibly combined with the rectifier possibly even water cooled.

I'd suggest you run it without a regulator initially . You will probably find no problems, esp if you have a good sized battery but if you run for long periods at high revs you may find you need to consider a regulator.

Hi thanks for the advice and I'm sorry to keep on the subject... but I want to connect my fishfinder to the battery afterwards and am worried about blowing it up when under way and charging the battery. Do i have a need to be concerned or not? and last thing is if i do need a regulator would any regulator do? like a motorbike one for example...

I mean if it's going to get pricey i may look into getting a newer engine with charging fitted hence can i get one as low as possible?

Many thanks again in advance...
 
I dont know the spec of your fish finder in particular what its max input volts is

I don't have a regulator and I have no trouble with my echo sounder, VHF or autopilot. The one thing I will say is make sure these are always run from the battery not from the outboard without the battery connected.

I know nothing about motor cycles so cannot say if a regulator from one will be suitable or not. If it's to regulate the rectified output from a lighting/charging coil then possibly.

A new engine with battery charging may still not have a regulator except for the very latest models. My outboard came with battery charging as standard equipment but has no regulator.

The article in Jan PBO is merely a circuit for using a readily available bridge rectifier including the facility to double the output volts. Its not a regulator.
I'd have thought the capacitors in the photo were probably 4.7μF. I'd have thought 4700μF would be much larger.

Sad that a Suzuki outboard has such a short anticiptaed life. 26 year old Evinrude still going strong and will see me out I reckon. Plenty of Evinrudes and Johnsons much much older still running in the US.

Brilliant Many thanks for all your help. I'm off to Get her to work... Many thanks again...
 
Im re-building a DT8 as a replacement for my smaller Yamaha 4hp. Twice the power should make all the difference in pushing tides this year around Orkney.

stand corrected ,,realize not a regulator ,, however

the author of article was the one that posted the correction .

and yes was a bit of an exaggeration about the suz' outboard !:) most small outboards seem to last forever if looked after and sometimes even if not looked after!! :)

Suzuki dt8c (88-97) dt 9.9c (88-97) PDF Manual

I have a dt9, and it only has two wires coming from the magneto. It does chuck out a small charge after being rectified though.

That's the parts book. Useful yes but not a manual as such

I have the manual but, with apologies to the two members who've PM'd me about it, it's far too large to email (72Mb!). hadn't really thought about how big the file is! I'll look at putting it up on a web server or FTP server in the next few days

Hello:

I am trying to figure out how to hook up this same rectifier on a Suzuki DT15 motor which looks like it's the same as the DT8. My engine has two wires, a black and a white, and I've checked them and they deliver 2-8 volts AC (depending on the motor rpm). I hooked the rectifier's yellow and white wires to them (white from engine to white on rectifier, and black from engine to yellow on rectifier), and I'm getting no voltage on the red and black wires coming from the rectifier. I do not have a battery hooked to it, I'm trying to see if the rectifier will provide any DC output voltage at all, which it seems to not. The rectifier got warm though. Any ideas? I'm not sure why I'm not getting any DC output from it. Thanks.
 
Being a new member it seems I can't PM. My apologies for posting to a very old thread. I'm looking for a DT8 manual. Any suggestions? Do you, Bru, still have one?
