Using a factory Tesoro coil for the TSGL kit

[gsignal888]

I purchased and built up the TSGL kit bought years ago but never finished it due to lack of spare time. Now I want to finish it off but still interested in building the coil for it.

Can I buy a factory Tesoro coil for it and plug it in and use it as is?

[silverdog]

yes as long as it is a 5 pin connector not the later 4 pin style

[gsignal888]

can you recommend coils that will work and plug&play on the TSGL without any tuning. I want to finally get this TSGL up and running as fast as possible.

[Tibuck19]

yes as long as it is a 5 pin connector not the later 4 pin style

Isn't the TGSL a four pin and not a five pin ?

[Nandor]

No, 4 pin configuration has 1mH Tx and 15mH Rx

[Tibuck19]

No, 4 pin configuration has 1mH Tx and 15mH Rx

So you would get a five pin Tesoro coil and how would it wire it to the TGSL ? which pin do you eliminate ?

[Nandor]

Well the 5'th pin is the shield, you can find the wiring diagram on the TGS topic or just measure the resistances on the pins. The lowest is the Tx and the other must be the Rx.

guys
this is base of tesoro coils from my archive

semi half of RX::
This suit to (5-pin connector) Tesoro models:
Silver uMax, Outlaw, Golden uMax, Euro Sabre II, DeLeon, Cortes
TX = 6.2mH, 20,5E, center-tap
RX = 8,6mH, 22E
newer tesoro coils have Ratio from 1mH tx -14mH rx (4pin connector)
older models 6 and 6,5 (5pin connector)

Well the 5'th pin is the shield, you can find the wiring diagram on the TGS topic or just measure the resistances on the pins. The lowest is the Tx and the other must be the Rx.

Ok what had me confused is that on the board there is only 4 connection points two for the TX and two for the RX, and the coil I have was made by a member and it was made with 4 wire connector, the ground or shield wire went to the TX and RX as shown in the photo .
So just to be clear if I was to buy this coil https://canadiantreasureseekers.com/...10-concentric/ It would work on my TGSL-EDU ?

[kt315]

main problem they never give useful information and give only garbage.
what you can know from

1 kg

30 x 20 x 10 cm

Tesoro

fully idiotizm. we must know instead of that -
1 - raspinovka of socket, pinplacement socket diagram
2 - resistance
3 - inductivity of rx and rx
4 - resonance frequency on rx side and tx side

Nice work Kt315, thanks for sharing it.
