What is your RETURN Policy ?

Yes we accept returns !

1./ Change of mind : 90 Days refund less 10% and postage costs.

goods require inspection for re-sale.

2./ Fulty Goods : We supply a replacement free of any charge to you.

we require proof of fault / purchase and contact tech support.

What is your WARANTY Policy ?

Most products 2 years. Except for competition use in suspensions parts.

My Blue light (high Beam Light) does not glow or is very dull.

Negative switching issues ! USE the GTW Harness or install load

COMMON to LOW and COMMON to HIGH beam.

What Load resistor do I use for 12 Volts ?

from 6 to 30 ohms with a power rating = 300 / Ohms

What Load resistor do I use for 24 Volts ?

from 12 to 100 ohms with a power rating = 1200 / Ohms

When do I get the goods - Installment plans

As soon as you make the first payment and have met our criteria.

What are your criteria ? - Installment plans

Email front and back of Drivers Lic to sales@ultraflex4x4.com

1./ It MUST show the same delivery address and paypal address

2./ The parcel will be sent with signature required.

3./ You MUST provide a mobile number that we can verify.

How are payments worked out ? - Installment plans

Payment one = (total/3+freight) two & three=(total/3)

i.e goods=300 post = 25 Payment 1=125 2=100 3=100 (125+100+100=325)

What if I miss a payment ? - Installment plans

We will email you,call you, then send to Sherrif after 30 days.

What is Negative switching ?

Constant volts to light COMMON and the EARTH is Switched to Hi/Lo.

Batt+ -> Light -> switch -> Batt-

The high beam light is connected across the low beam switch

Accessories connected to a "Floating" ground and they all have a coil

connected to +BATT so the volts will not drop unless there is a load.

If the volts do not drop then relays (coils) will not turn off.

due to the lack of difference between battery and floating earth

the low beam light will not work. Add a load to stop the FLOATING !!!

What is Positive switching ?

Constant Earth to light COMMON and the POWER is Switched to Hi/Lo.

Batt+ -> swtich->Light -> Batt-

Does Positive switching have issues with High Beam Dash Light or accessories ?

No it has no issues . Plug and play. No floating voltages.

LED lights plug stright in. Nothing required.

Is my car Negative switching ?

Most cars after 1985 changed to Negative switching . Why - Cheaper.

The following are Negatively Switched

Toyota All (except some holden variants)

Holden Rodeo (re-badged and co-built like rebranded toyotas)

Mazda Imports

Subaru ALL

Daihatsu ALL

Suzuki All

Do I NEED a GTW HARNESS for Negative switching ?

NO. If you have a virgin stock car . You can use the off road harness

You do not need the off road GTW harness

If you have Light bars and Spot lights .. Or some funky wiring. YES

If you do not like to spend 2 hours on dianosing issues .. YES

Which cars are Positive switching ?

Not many these modern times. But generally -

Landrover

Holden but not re-badge or co-built

Ford

Nissan

Kenworth

Jeep

What is the difference beween GTW and Offroad HARNESS ?

The GTW has inductive oversized load resistors for 12 and 24V

They draw around 5 Watts in 12 V Systems

They draw around 10 Watts in 24 V Systems

My car is Negative switched do I need GTW HARNESS for 100W+ Halogen ?

Same rules as 14 apply. If you have fruit you need more fruit !

The GTW harness is ALWAYS recommened for Negative switched.

My car is Positively switched do I need GTW HARNESS for 100W+ Halogen ?

Same rules as 11 apply. If you want fruit, add more fruit !

The GTW harness is ALWAYS recommened for Negative switched.

HOWEVER it can be used on both equaly well.

My LED lights are making radio noise RFI (negative switched) !!!!!

Dirt ! And Corrosion ! USE the GTW Harness to prevent these issues.

Very rare to come across this issue.And has Never been the Lights.

1./ Check all earths and Power on battery, guards, harnesses

Clean the conections and apply grease to keep out corrosion

Corrosion WILL act like a crystal oscillator

2./ Check by removing one Ultraflex4x4 LED light and pluging in

a normal halogen globe into that socket ..in the NEW harness.

If the noise STOPS then the relays in the harness are dirty.

3./ Put a halogen globe into the unused OEM harness and test.

If the problem goes away the the EO head light relay needs

replacing. It has corrosion, carbon, or pitting and is acting like

a oscilator under low current draw.

4./ Make a good ground from Antenna base to Guard and

guard to chassis . Make it about 6 mm thick . Take off paint and

grease the connections to stop corrosion.

5./ Put a LOAD resistor see (3 & 4) in the OEM Harness

from COMMON to PASS and COMMON to DRIVE

or COMMON to LOW and COMMON to HIGH beam.

6./ A faulty Alternator can force the buck boost converters to rapidly

Switch modes. This would be a Diode or Regulator OR the Battery

is almost dead and is not damping other Noise due to lower loads.

Is Ultraflex4x4 interested in me distrubuting products ?

YES . Of course. Please call the boss and ask that question.

NDA's are required.
