Starter problem

Postby paneuro » Tue Sep 08, 2020 1:05 pm

Hi, I'm having a problem with the starter on my 2006 1200rt. I didn't use it last year due to health problems and decided to maybe get a few miles in on it this year. It is kept on an Optimiser all the time but when I went to start it all I'm getting is a click at the starter, I checked the battery and its showing 13.60 volts on the multi meter so it would appear to be ok. I have checked the battery terminals and they are ok but have not pulled the plastic of to have a look at the starter terminal. I assume the starter is ground via the bolts and its just the one terminal I will have to check. Anybody got any other thoughts? what plastics have to come off ? is there an earth/ ground terminal from the engine to the frame ? TIA Paneuro

I am fairly confident that you are only seeing "Volts" and not amps Amps is the "capacity" as such So the voltage may be okay and the battery will have the capacity to light a headlight for example but when the starter demands amps / current it cannot supply enough hence the hammering starter solenoid

A simple test would be to park your car beside it and connect jump leads across to the bike (Car engine NOT running) and just see if the extra capacity will spin the bike over (use decent leads Cheap ones are a nightmare and a waste of copper wire

I suspect the best course of action is to remove the battery and take it to a battery specialist or an autofactors near you Where they can actually test it to be 100% sure

Hi Jaythro, all fixed, I stuck it in gear and turned engine over, hitthe starter button and bingo started first pop. I have tried it about 8/9 times since over the last 24 hours and no problems so if it ain't broke don't fix it but thanks for your input. Paneuro.

Hmmm,

You might want to schedule in a starter rebuild in the near future. I can see two possibilities for what happened... ok, more than two but these are the likeliest.

1) The starter armature came to rest with a bad segment of the commutator contacting one of the brushes.

2) One of the brushes was stuck in it's housing and not contacting the commutator.

In both cases, it's likely to recur eventually and may not be so easy to clear next time. A strip, clean and electrical check might save you a lot of grief in the future.

I replaced the starter on my '06 RT with a fully rebuilt one when I became convinced it wasn't doing its job properly. The one on your bike is quite possibly a Bosch one - BMW swapped to a Valeo unit in, I think '06, but some '56 plate bikes still had the Bosch, no doubt because they were using stocks up. The Valeo is physically bigger, and has more starting oooomph - it's a straight swap for the earlier one, made easier, from memory, if you disconnect the gearchange linkage so you've got a bit of extra wiggle-room. I got mine from a place in Oldham, listed on eBay (under car spares!) - item number is 302952695190. Well worth considering, as if you rebuild the Bosch it'll still fall behind in starting power, the Valeo spun my RT's engine over noticeably faster.
