Searched but can't find

OK, everybody knows I'm the new kid on the block (both to the forum and to GS's).

I'm about to embark on a purchase of a 1982 GS750T, the problem is (and this is a quote from the seller) "When it starts it blows the fuse in the fuse box, somebody told me I needed one of those rectigators ? or something like that".

Now, my question here is: Does this sound like a "Rectigator" problem ??

If so, I will go ahead with the purchase and before anymore damage is done, replace the "Rectigator".

Thanks rectigator !!!! LOL

Rectigator? isn't that which happens in florida when you hit one with a car?

rectifier/regulator... rectigator? yes it sounds like the r/r but check it if and when you get it home .

Nah, here are the Regulators MC:

Check it ????

Let me see if I got this right......

The Stator produces A/C current while the bike is running and transfers it to the Rectifier which turns it into D/C current, then it is pushed out thru the Regulator and back into the battery at 12 to 14 volts.

If this is correct then I should not receive a reading of more than 14 volts coming out of the R/R...........right ?????

If I get a reading higher than 14 volts, this could be the problem of blowing fuses because it is pushing more voltage thru the electrical system than it can handle...............correct ?????

Thanks

You are correct, Smurf. But you should be fine with voltages up to 15vdc - mine currently runs 14.4vdc on warm afternoons and about 13.9vdc on cooler mornings.

Thanks Mark,

I'm not new to motorcycling nor Suzuki's (I started on a 1998 GS500, now I have an 05 M50) however, I am new to the older GS's and trying to learn about "Rectigators" LOL

Thanks for the info.

The charging systems are the achilles heel of these GSs, specifically the r/r and/or stator. All the info you need, including a description of the charging system and tests to determine how yours is working can be found in the Stator papers here...

Good luck on the purchase of your 750!

Thanks JT,

I'm going there now.

Hey !!!

One more question: Could I take the battery out of the bike, hook jumper cables to the bike cables, and disconnect the R/R then replace the fuse and start it up ?????

If the R/R has gone bad but the stator is still pumping out juice, disconnecting the R/R would stop it from blowing the fuse because the bike would only get power from the other battery not from the Rectifier and Stator.

Is this stupid or am I thinking "Outside the Box".

I'm not biting your head off here, but you need to learn how to use the search function better.
As stated on this forum many times: You can run the bike for HOURS with the charging system disconnected, if you've got a fully charged battery and the headlight is off/disconnected. If the fuse doesn't blow with the charging system disconnected then you've got a bad charging system component. If it still blows, then you've got a short elsewhere.
Do a search for further details. Also, see the many posts about the check-list of verifications needed when restoring a bike. You'll save yourself tons of time, aggravation and money. In the end you'll have a reliable bike for a fraction of the cost of a new one.

I apologize,

I did'nt find the answer I was looking for. You however did give me the answer.

Thanks, I will do better next time.

[nabrams]

No apology necessary. We're here to help. When I first started on this forum several years ago, I got the same advice about using the search feature. Also, I was told to get a good manual to use in tandem with the info here. Being the timid, fairly inexperienced mechanic I was at the time, it took me a while to actually dive in and follow the advice here. Since then I've restored at least five non-running bikes to daily riders. Invest a couple of hundred dollars into tools and put in a hefty amount of time and effort - you'll be glad you did. It's a lot more rewarding than sitting in front of the TV.

Thanks Bud

This will be the first bike I have purchased not running, and I'm a little sceptical about forking out the dough if I can't get it running. I was given a 78 Kawasaki KZ650 that was going to be thrown away, gave it to a buddy of mine bacause he said he could do the restore........(we all know where that went). So now it will be coming back to me in pieces.

Thanks for the advise.

Yes it can and does regulate above 14v d.c. and you more likely will have a reading from the mid 13's to the low 14's

If I get a reading higher than 14 volts, this could be the problem of blowing fuses because it is pushing more voltage thru the electrical system than it can handle...............correct ?????
Thanks

No, the fuse is an amperage rated device (10a, 15a ect.) you could have 24v going through it at less than it's rated amperage and it would not blow, the electronics would not fare well but it would not blow until something shorted and drew more amperage than the fuse was rated for.
most likely the regulator is shorted blowing the fuse but there are other possibilities like a shorted wire to ground, corroded connections, to name a few.

yes, but don't have the vehicle running when doing it.

Power will be gotten from your battery and the other battery.
disconnect the stator from the r/r and the r/r from the bike so as not to damage the stator.
