240 '93 starter problem

Hi !
I have a problem with the starter. In fact when the engine it's hot the
starter doesn't turn because the solenoid doesn't close the contact. If I
wait a quarter of hour it goes regularly.
I tryed to supply directly the solenoid from the battery while happens how I
saied before and it's all normal!
So I think that's a relay's problem but I don't know if there is a starter
relay and, if so, where is it??

Thank you and enjoy your VOLVO!!

 

The 240 does not have an external relay, it is all contained within
the solenoid.

Assuming your cable connections are clean, the problem is within the
starter / solenoid assembly and it will have to be unbolted and either
repaired or replaced.

 

The best solution is to replace the starter/solenoid assembly with a
rebuilt one. Getting the upper bolt out can be a pain and will require
the creative use of socket wrench extensions, etc. Also the thing is
heavy, so don't drop it on yourself pulling it out!

.....But I think that the solenoid it's ok because if I give tension directly
by a bridge from the battery to the solenoid it closes the contact and the
starter turns regurarly . So I think that the problem It's between the key
block (I don't know the right name in english....where you put the key for
switching on the car) and the solenoid.

 

Is the car an automatic? If so, check the neutral safety switch in the
shifter assembly. Try wiggling the shifter when the car won't start.

 

I repeat that the problem occours only when the engine is hot after 3 or 4
hour

Thanks, Andrea!

 

It's possible that the solenoid doesn't get quite the same current
through the "normal" setup as it does with your "hotwire". And,
certainly, solenoids do get sticky, and often when they are hot.
So..... wait until the next time it refuses to start, then jump out
with the 12 volt bulb with long wires with clips on the end which you
have prepared, and clip it to the solenoid connection and the ground
and stick the bulb where you can see it from inside the car, then try
to start it again, and if the bulb lights you know that the voltage is
reaching the solenoid and the solenoid is bad, and if the bulb doesn't
light you know that something before the solenoid is bad. Like the
relay.

oh by the way, how is the battery? sometimes a battery can be almost
dead, and possibly in that case the difference between the normal
setup and your hotwire setup might be enough to get the solenoid to
close. Maybe. Possibly.

 

240 Starter assembly is one of the easier things to do by the average
do-it-yourselfer. It's about 1 step above cleaning the automatic window
switches and costs about $12.

All (or nearly all) 240s and 740s and 940s can share the same starter motor.
At your local pic-n-pull junk yard, take your ratchet wrench set, including
a few short and long extenders and one of those ratchet wrench u-joints that
can wobble a bit. I think it's only 2 bolts that you figure out when you
get under there. Experiment with different combinations of wrench extenders
(4 inch, 10 inch, maybe even 2 10-inch extenders).

I pulled about 4 of these, as they also fit 140, 122, and 1800, all of which
I needed on projects.

Installing is reverse of removal.

 

One thing about these is it's a lot easier to change on a manual
transmission car than automatic. The upper bolt on the autos is a really
tight fit. The 700/900 series has a lot more room there.
