Cali 1400 Electrical Issues

[rrojaswahl]

Friends - after ~ 100 K miles now the electrical issues are starting to get worse on my 2014 California 1400 Touring:

Red triangle comes on, big SERVICE letters appear, and while the bike still runs for ~ 60 miles or so, eventually the ABS and traction control lights come on and then I allegedly drive 247 miles per hour, hence the whole display goes nuts, and then the bike dies.

It's not mechanical - it's electrical. When I diagnose the errors stored the ECU I get the following codes & descriptions (translated from German):

P0610 - brake light relais too low
P0700 - A-PRC function error: no signal - what does this mean, what is the PRC function?

both have appeared on two occasions by now.

then also recently the following two codes appeared alongside those above:

P0560 - Battery voltage : too low (even though I had just recharged the battery btw...)
P0701 - no signal - again: what does this mean?

Is this an alternator issues, hence the battery not charging? Or are there other underlying issues that I don't know about?

Is a new alternator the only remedy here, or has anybody had a similar issue and fixed it differently?

Many thanks & cheers,

Roy

I haven't had my 1400 for about 4 years. First thing check the voltage first thing while it is running, This can be done using a function on the dash as you probably know. I would replace the battery, they are cheap, at least in the US. If you don't have one I would get the Service Station manual. There is a complete list of error codes in it. There is a guy who sells them on eBay. He goes by "meandmylittleman201 5. I have purchased several manuals from him. You can also get a digital version online from Cadre Cycle. Good luck.

I sent you Pete Roper's email address by personal message. He knows what is wrong and will walk you through it. Just click on "my messages" above, copy and paste the address in your email browser, and send the message to Pete.

Oh man, doesn’t Pete post here any longer?

The man’s an absolute legend, in the very good way for the Moto Guzzi community. Years ago I bought one of his sump devices to help prevent the oil pump from starving for oil.

Plus he’s as funny as the day is long.

Many have left Mark, Beetle's gone too. I won't get into who insults who. None of my business.

Pete is easy enough to find, Griso Ghetto

First look at voltage with running engine, clean battery terminals.
Aprc is Aprillia traction control, or the Guzzi variant,
But the combination of errors points to missing voltage. Or connections or the generator or is regulation device buit in the generator as a replacable unit.

+1 Paul, there was an update to cut a wire to Alt that will fry it if key is left on. AND the wire was still coming hooked up even in 16. The wire was to go to a GEN light but bike doesn't have one.  Do a search and you'll find it.

The Voltage regulator is internal to the Alternator, I have no idea if its a replaceable item, All I can suggest is to read the battery Voltage, should be 13+ at upper revs.
Im pretty certain the green wire to the Alternator should be alive with the motor running (Power thru Fuse 1) Do the horns work? they share the same fuse

[guzzisteve]

The alt can be rebuilt & the regulator can be replaced, friend in IL just had this done for $100 bearings and all.

Friends - txs for all the help and comments and ideas!

To answer the questions posed below:

1) When the defect happens and fuse 1 bursts, both horn and front-light go out. Daylight running- & rear-lights stay on. New (!) battery reads ~ 11.4 V after a ~ 50 mile ride with warning light on, so not close to 14 V and hence not charging during the ride. When I rev the engine, voltage of battery does not increase - again evidence it's not charging. But why not?   

btw : Alternator rebuilt and regulator replaced for 100 dollars? Where?? Or do you mean 1000 dollars?

Many thanks again,

Roy

You can get a used one on ebay or take it to a rebuild shop. My buddy took his to a shop in Geneva, IL that's been around forever, they put in new bearings also. I would check everything on that fuse circuit for a pinched wire or bad connector.

Clean all the ground wires too.
