Heater amp connector

[shep1001]

Anybody have a link or know where I can purchase a replacement 6 pin connector for the heater amp? the board is OK its just the connector on the loom end (car) that has melted a little! and I cant get a good connection.

I just refitted mine last night with exactly the same problem. Finding the correct connector block was impossible so in the end I soldered the 4 wires straight to the board with a pin to each connection hole, each sleeved in shrink-wrap and bonded in glue.

Whilst the connector block was burnt out, the two capacitors had gone as well so worth checking if the rest of the board is OK - there is a company in Luton that will refurbish them for you if needed for £50 - there was a post on the forum a few weeks ago giving the details.

Also, I've relocated mine to the passenger air vent to aid cooling as shown in Graham Varleys manual. My geek of a friend looked at the unit and pointed out a design fault in the circuit which causes them to overheat so worth relocating them.

Thanks for the info. The company you mention is down the road from me, the unit itself is fine its just the plug that is iffy. Might try maplin, failing that I will solder and shrink direct to the pins.

have you got a picture of the connector?

I had exactly the same happen to me some years ago. I think I ended up coming up with a solution as suggested after failing to source the connector. I'll have a look through to find my original thread on here. Here are te images though:

Beats mine, thats well toated. There is very little melting if any, just a dodgy connection, might take the pins outand have a look at them first.

Here is the a discussion on this topic from 2008: http://www.pistonheads.com/gassing/topic.asp?h=0&a...

After reading my post back then I remembered what a pain it was!

NickT said:

I had a problem with my connector as well (it melted slightly causing a very bad connection which would require the passenger to constantly wiggle the wires until a good connection was made and the air-con would start working again).

I got a new connector from TVR Power just after the factory closed... it was a nightmare to source... that wasn't the problem though, getting the pins to slot inside of the connector proved impossible I ended up having to cut (well more like melt due to the plastic being so hard) the pins out of the old connector (with a short length of wire still attached) and then clean them up as best as possible and slot them into the new connector. I then re-connected the wires to the loom using standard bullet connectors. It worked in the end but not ideal! I had to slightly bend the pins on the amplifier to ensure a good connection with the clip.

Any idea where to get the pins for the inside of the clip (although now I suppose I would have to get the whole lot as once those pins are in it is very hard to remove them!).

Oh, and the brown stuff on the connector is glue not burning, from where it was glued somewhere near the carpet I guess.

I think the heater amplifier is put under load and therefore heats up the wires when you run the fans low from what I remember Dom at TVR Power telling me. Since then I run the fans at full all the time just to be safe

Hi All,
Old topic but I have just bought a TVR T350T and the blower has stopped working.
Waggled the connector on the amplifier board and that made it work.
New connector required I thought so bought a new Souriau connector and pins having found another thread that detailed all the required parts.
Just spent a few hours soldering a new male half of the connector to the PCB and then extended the loom with new female half of connector wired in.
Connected everything up expecting success in the form of air flow from vents but nought....
The blower will come on if I push down on the connector?
Seems that something else is not quite right apart from the connector as all new pins and sockets must be making a good connection I would think.
Someone further up this thread said a company in Luton can refurbish, does anyone know their name and address or website?
Thanks for any assistance.

Cheers,

Steve

With the unit out of the vehicle use a multimeter set on Ohms and push on the connector to find what's causing the open circuit

[FroxmereST]

Thanks. Will try that.
I did check connections between new pins and components (with ohms test) that are obvious on the back of the circuit board and all pins tested appeared to be making good connections.

FYI to all reading this, I had to buy more than one set of connector components due to minimum orders so if anyone is after a new connector I can assist in supply as have several sets left.
One connector set = 1 x Male and 1 x Female connector half plus 2 x small female socket pins and 2 x large female socket pins. The new Souriau harness half of the connector has strain relief legs to support the incoming harness and eliminate cable pull on the pins. Much better than the originals.

Cheers,

Steve

Hi Steve
I'd like to have a set of parts please, if the offer still stands. I can't email you directly as your PH profile won't let me. You should be able to email me via my profile page.

Thanks

Hello Steve

I have also had similar problems with Sag heater amp , I would also be interested in components if any are left , please contact me via e-mail on my profile if you can help . Many thanks in advance

Not sure if this is against forum rules????

When I made one up for my car I also made an extra 3 sets. All have longer wiring to enable re-location within the cold air duct, the male plug which sits on the circuit board is also included, just in case you wanted to change this out. The wires come already connected to the female plug so you would just need to cut and reconnect.

Email me if anyone is interested

Good thread resurrection - 7 years. I can confirm relocating to the heater vent works well as mine is still going 7 years on

[konrad.holl]

What I had done to cure the problem, looking at the situation this way:

• Obviously, the current is too high to pass through a single pin
• There is one unused pin on the connector

I simply added a wire to the connector and "bridged" the pins on the circuit board side. Now the current is passing through two pins - no problems since.

Konrad.

Hi all. Convenient for me that this topic was resurrected too. I bought a Tamora a few weeks ago with a few known problems to sort including the heater fans not working. I assumed it was the normal connector problem, but turns out I'm missing the heater amplifier circuit completely! Options?
Any sources of new or used boards?
Any details of pinouts or full circuit details so I can make a new one?
Any way I can bridge the connector pins temporarily so I just have full on/off fan control?
Thanks for any help.

Think I've seen them on ebay occasionally. Maybe Paul Smith of PS Electronic Solutions can help, he refurbishes them so may have a source.

I emailed Paul earlier today hoping he may be able to help. Fingers crossed. Will keep an eye out on Ebay but not many T350s or Tamoras being broken. Steve Strange who's got some t350 bits on there hasn't got one. Thanks. Huumm...

Jody at Python racing does a lot of TVR stuff too, Using him currently to get a door ECU done, have used Paul in the past but he is notoriously difficult to get hold of.

[subseamatt]

Ta, have emailed Jody too. I've got Str8six just down the road too so will see if I can speak to them during the week.
