Wedge List / Re: TR8 Alternator
« Last post by Greg Gall on April 12, 2019, 09:17:38 AM »
Hi Richard,



Many on this side of the pond have done the conversion to a Saturn CS130 of

CS130-D alternator.



Here is an image of a CS130-D, which is what I used in my TR8:

(Just found it on Google - not TR8-specific).



You will have to clock the alternator (rotate the face 120 degrees), swap to a

V-belt pulley and make a small adapter harness...

It is good that your are checking the check valve first.B  The other possible

cause is a ruptured diaphragm in the booster.B  But check the valve first as

it is easy and it is cheap (relatively) if that is the cause.B  You can remove

it and try blowing though it in both directions.B  If it has failed you will

be able to blow though in both directions.B  If it is good you will not be

able to blow through it in one direction and you may be able to in the other

direction with some effort.

Wedge List / TR8 Alternator
« Last post by "Richard Connew" on April 12, 2019, 04:19:30 AM »
Folks,

For years I've always taken the original alternator off my TR8

EFI to a local recon guy who has sorted it out and its gone back on the car

with new innards as required. Sadly after many years his business has now

gone so it looks like I need a new 25 ACR alternator. The wiring is the old

terminal type on the car where as the new ACR alternators all seem to be a

three pin plug fitting. Amazon have this adaptor plug

https://www.amazon.co.uk/dp/B07GJTB9ZK/ref=cm_sw_em_r_mt_dp_U_DJeSCb6FNR2WA

See this Alternator on Ebay https://ebay.us/mCZigo albeit an 18ACR. Manual

says 17ACR - 25ACR so maybe with a higher amperage 65 and the fact I don't

have AC this one would work.



Appreciate hearing what folk have done when replacing alternators?

Many Thanks



Richard

My TR 8 has it in the line but it could have been changed before I got it

25 years ago.  Regardless summit also has generic booster mounted ones,

even in chrome.

Ben,







This part plugs in to the vacuum booster similar to TR6, hose goes on the

other end.  It is not the in-line kind that TR7s have.







Thanks.

There are generic parts.  You just need to know the hose diameter.  I saw a

couple on Amazon, summit or even the local stores.

Wedge List / Brake booster non-return valve
« Last post by "Paul G. Edelstein" on April 11, 2019, 08:40:50 PM »
Greetings, all.



The non-return valve on my TR8 brake servo/booster has stopped working -

i.e. it no longer holds the vacuum in the booster.  When I shut off the car,

I can feel the pedal get hard in a second or two.



The part number for this item is 37H8278 (from TRF and Rimmer catalogs), but

it is no longer available or no longer supplied by any of the usual sources

(TRF, Moss, Rimmer, others).  Does anyone have a source for this part, or a

workaround?



Thanks in advance.



Cheers,  Paul E.

First of all there is nothing wrong with the light switch since the other

light works fine.B  A problem with that switch would effect both lights in the

same manner.

There is a switch in the pod that responds to pod position and will cause the

motor to stop when it reaches full up or down.B  The light switch will power

up one of two wires depending on whether the lights are ON or OFF.B  The

switch will connect one or the other wire to the relay and the relay will then

control the motor.B  Each side has its own control in this respect since the

motors can run at different speeds so a common control would lead to a loss of

synchronization. B B  Since it goes up the motor circuit is fine and the lines

that control the relay for UP are fine.

It could be a bad switch contact or the diode in that circuit is faulty but it

might just be a dirty contact in the connector.B  As I always say (but don't

necessarily follow) check the easy stuff first.B  There are several connectors

leading to each headlight assembly.B  One is for the headlamp itself.B  One is

for the motor and the third is for the relay control circuit.B  This is a

three-pin connector with a Brown/LightGreen wire, and Blue/LightGreen wire and

a Green wire.B  Unplug this connector and plug it back in and see if that

fixes it.

Since the left pod works and since the wiring runs to the right pod first and

is daisy-chained to the left, the odds are very good the harness wiring is

good.B  Worst case scenario is you would have to replace the pod mechanism.

Good luck.

Hi Terry, check out my website www.tr8archive.co.uk click on Tinsey's Tips and

then on Head Lamps. There you will find a very detailed report on the head

lamps and also on fault finding. Ian has worked on TR's all his life and owns

his own garage. He also owns the prototype TR8 FHC which he completely

restored in the 1990's. I hope that this will help.

Have you checked the contacts in the motor?



It is a wiper motor and I think the self parking contact is used to stop

motor at each end of the light up/down operation and give opposite function.
