Anyone had problems with the electric throttles on a Volvo D6-370 in Targa38?.
Went out today and was able to engage forward thrust on the out drive, but couldn't increase RPM above idle. Able to select reverse and increase RPM ok, in Neutrel engine would run up to the 1500rpm limiter. Other engine was ok
Any thoughts?
 
Most likely the microswitch in the throttle quadrant playing up, if the EVC system doesn't detect that you have selected forwards it will only allow limited rpm. Might get away with trying to adjust it or replace its very easy, it sits inside the black base on the lever shaft.

If it's the earlier evc there is a neutral switch in the shift actuator check to see if the neutral light is lit when it's in forward gear if it is then you will only attain 1500 rpm, you will need a new shift actuator
 
Thank you spannerman,
I'll have a look at that, do you know if the micro switches are a Volvo part or can I get them else where
Thanks Ian
 
I agree with Volvo Paul on this. If neutral light staying on then it's normally the gear actuator. Change actuator, gear cable and check if your outdrive falls into the batch with dodgy gear selectors (only on early DPH drives)

If it is the microswitch you may be able to get one from Maplins, its a fairly standard design.
 
Thank you for all your replies Gents, they been very helpful. What does the actuator actually do? does it only select forward and aft gear via the cable on the outdrive?. The gear will engage ok but I cannot increase RPM in forward thrust, but it will increase RPM in reverse
thanks

Which generation evc are you ? Do you have a display in the rev counter that shows temp , oil etc?
Have you had "check engine" come up in the display , an alarm ? If not it's the neutral switch in the shift actuator , unit it sealed .
 
Not sure which generation the EVC are, but I do have the displays in the rev counter. No "Check Engine" message or alarm, so it looks like the neutral switch in the shift actuator then.
 
Just an update on my problem, after all your advice, it looked like the actuator was my problem.
I managed to get secondhand serviceable unit and swooped it over. With gear selector cable disconnected the engine rpm was normal, however when the cable was reconnected (and drive in gear) the engine rpm would not go above idle.
A local engineering company thought it may be a seized out drive!.
But a quick call to Volvo Paul, he ran me through a few questions and quickly diagnosed that the neutral light was still on with the outdrive in gear, therefore the neutral switch in the actuator wasn't being made.
I shortened the shift cable by two turns, reconnected it, and low and behold when the neutral light went out and the rpm increased normally. Just got to wait for my next day off to sea trail it, but fingers crossed all looks ok.
So thank you all for your advice, and special thanks to Volvo Paul, more beer I owe you.
 
Sea trial went ok yesterday, but I noticed the shift cable was very stiff on the troubled side compared to the other engine, so for piece of mind I'm thinking of changing the shift cable before the EVC actuator gives up.
Any advice on changing the cable ?
thanks
 
After suffering a broken throttle cable a few years ago, the local Volvo agent told me loads of them were breaking every summer, so while waiting for the replacement, I lubed up the other one, and it transformed it! Now three years later the old cable is as smooth and free as the other engines newer one. I lube them every year now, takes a few minutes with some tissue, and some spray oil (Not WD40)

Might worth the issue out at zero cost!?
 
Hi There
I'm having a similar problem with a Volvo Penta D6. I am getting an error code 2.3.5 which is a 'Shift Actuator Problem'. When i select forward gear the boat will go forward at max 600 Rpm when i try to increase i get the above alarm and the engine shuts down. The cable has been replaced in the last couple of months so I'm ruling that out and the actuator seems to be working properly when the cable is disconnected i.e going into forward, reverse and neutral position. The rpms on the engine will also will also increase once the cable is disconnected. There's also no issues when all connected in reverse.
So i guess my issue is with the Actuator. I didn't know there was a neutral switch in the actuator. Is this in addition to the neutral switch in the throttle. I presume it's can't be replaced or repaired. Any help or in put will be greatly appreciated.
 
Hi Jason,

My problem turned out to be cable adjustment. I didn't get any error codes. Can you get an increase in Rpm when selecting reverse?. On my EVC display I have neutral lights and that light didn't go out when selecting forward but did in reverse. Shorting the cable a couple of turns sorted my problem out. Marine Tech at Gosport had a secondhand actuator.
Hope that helps
Ian
 
Thanks Ian
I'll have a look at the neutral switch lights as per VolvoPaul. I can get increased rpms in reverse. Is it just a case of turning the cable a couple of times while it's in position as is.
 
Yes it was just a case of disconnecting the split pin, undoing the locknut and winding in a couple of turns.
Remember to keep count of what you do
 
HI Ian/VolvoPaul
Thanks very much for your input. A small adjustment resolved the issue. I actually can't believe it. The last time it happened the boat had to be taken out of the water & was out of action 5 weeks in a local Volvo workshop trying to resolve the issue. I also received a very hefty bill and i'm not talking hundreds it was thousands. (how can those guys not know this) I definitely owe you guys a few beers. For any issue in the future I know where to call to first. Thanks again.
