Adding lights and heated grips to a 93 R100GSPD can the electrics cope ?

[twowheeltrekkers]

Adding lights and heated grips to a 93 R100GSPD can the electrics cope ? I know it has a 280 watt alternator and I know my 1980 R80 did not cope with lights on and heated grips when I was using it in London all day years ago, I seem to remember that there was a different regulator fitted to Police bikes that helped with the charging

Any help on this would be appreciated

You’d probably use LED lights these days that would use a lot less power so you could manage with the heated grips and aux. lights on.

The police regulator just kicks in at lower rpm which means the battery is still charging when the engine is ticking over which will help keep it topped up especially when driving in traffic.

As Chas suggests, LED spots will reduce the demand on the battery. You might consider an LED tail/stop light also. I’d suggest you take the power from a separate fuse board to minimise the rat’s nest factor and spend a bit of time cleaning earths etc in the rest of the wiring harness.

If you have some free cash you can go the Silent Hektik 400W Permanent Magnet route. Then your concerns are over.

I did this on mine.

Silent Hektik 400W Permanent Magnet route.

I'd like to see this and hear about any issues you may have had dealing with Silent Hectic as a supplier....

I did a little thread.

I hope that works.

I have nothing but praise for Silent Hektik.

I bought the alternator through Bayer BMW but I called into to Silent Hektik on one of my trips around Europe and bought the blanking plate for the bean can as I changed the ignition later and forgot this.

I'm very happy with how it fitted and works.

Expensive .... yes but the quality just can't be improved upon.

I have just rebuilt an early paralever R80GS. It already had a 450W Enduralast charging system.
I fitted new genuine BMW heated grips. Checked current with a clip on dc ammeter. Current draw was less than I imagined, on position 1, hot only 3 amps

Thanks for the info, the Silent Hektik kit looks good but sound a bit to pricey for my liking

I plan to change the headlight bulb to an LED one that consumes just 25 watts, that should give me 30 watts to play with, if I fit a pair of Denali D2's that will be 20 watts used but I also want to be able to use heated grips and occasionally my Keis heated body warmer, that only draws 1.8 amps so about 20 watts, I figure by adding the police spec regulator it might cope with all this

The alternative plan is to fit the new Denali DataDim Smart controller and D3 lights that should arrive in the shop in the next week or two, a pair of D3 lights will draw about 60 watts, even converting the headlight, rear light and indicators to LED and with the better regulator I think this set you would be too much for the standard charging system, for this set up I was thinking about the Motorworks alternator upgrade kit that give a much higher than standard output of as much as 600 watts, I have also found Seibenrock have a 400 watt alternator conversion which costs about the same but will be subject to import duty now we are out of the EU

Open to feedback on which way to go

If you can find a good LED headlight bulb let me know please.

I have a stock heated grips and installed voltmeter instead of rev (never liked it).
Once i flip the switch to position 1, voltage (while driving) drops by 0.5V(13.4V) and when i set it to 2nd (more heat), Voltage goes down by almost 1V (~13V).
I’m planing to get aux lights too but not before i upgrade my alternator. And i had AdvMonster LED bulb upgrade, a bit better but still mediocre.
Good pair of Denalli’s can do the magic, everything else is just waste of money.
But yes, i’d strongly suggest to upgrade your alternator to 450w enduralast or 600W better (Motoelekt)

I tried several LED headlight bulbs, mostly from China, most of hem were crap but these ones we ok, cost about £25 for a pair, I fitted these to several CCM GP450's when we were selling CCM, this saved about 30 watts and thus allowed me to fit a pair of Denali D2's to the bikes for customers that only had the standard alternator, they are not an improvement but were ok

Endualast looks good to me as it appears to get rid of the diode board and the regulator and combines it all in the kit, trouble is they are in the States and showing no stock

I think Motobins or Motorworks has them…

Yep... the Enduralast is a single phase device. So all it has is a regulator.

 

[twowheeltrekkers]

Just looked and Motobin show it in stock so will be ordering after lunch (they close for lunch!)

 

[Steptoe]

The electrics can cope as long as you aren't riding in London (or any other busy city) all day every day. .

I should know, i've been riding air-cooled twins in London with heated grips and clothing since 1980 without any problems.

Mind you, it doesn't get that cold in London that you only require them on now and again.

Back in the mid to late 80's I was working as a DR and treated myself to a brand new R80RT in white, thankfully it had a kickstart as by mid afternoon riding with my lights on and heated grips the battery was flat, I used to wheel it in to the office every night and put it on charge, it was a BBC bike, one of about 20 of them that had everything it needed fitted, this one was still left at Park Lane so I picked it up at what seemed like a good price, good bike apart from the charging and the most uncomfortable seat, it replaced a CX500 which was all day comfortable

Enduralast 450w alternator kit ordered from Motobins, that should mean no worries about charging and flat batteries

Next I need to look at brake upgrades as the single disc is not much good and neither is the rear drum brake

Personally would not have gone this route unless the OEM alternator was goosed. LED head and tail light bulbs work plus the “police” high output regulator/rectifier is enough. I run heated jacket and grips with lights on no problem.
