When we have a problem at early model control system, people tend to install manual switch.
IMO, it would be a good idea if you try/set up self controlled system from other source other than manual switch.
We already developed new 11V self regulating control system in my shop to replace those manual switch/ faulty 6.2 V system.

Steven,
Could you please elaborate on this? Sorry if it was covered in another thread.
- why would it be an 11v system instead of 12v?
- how many have you guys installed and what has been the result?
- cost of hardware?
- can it be installed by someone handy with a soldering iron?
- does it require a specific glow plug or are there several it will operate properly with?
Look forward to the information, thank you.
Artie
Hi all,
I'd like to reply to OP's questions like below.
- why would it be an 11v system instead of 12v?
**In the glow plug control system, what kind of resitance the controller does supply electricity to the glow plug? This will be the answer.
Our delica has a 12V system. Why do we have 12V, 11V or 6.2V glow plugs according to model year? The answer is resistance value that each glow plugs have. Because of the resistance, we have a voltage drop.
All power group ( wiper motor, door lock, starter motor, connector , etc ) are a kind of resistance in view of whole electric system. Resistance is a heat.
Therefore The reason we have a 11V system is we have different control systems based on resiatances from the system.
- how many have you guys installed and what has been the result?
** Generally our customers have been very quiet in this forum. But they have raised issue if our service level do not meet their standard.
We developed this new system 2 years back and we installed appro.35 customers so far.
I’ve never seen any complaint for this service in this forum or other source.
We import and sell only 11V Hyundai OEM GPs.
The key to understand the logic behind glow plug control system is 'CURRENT' not the voltage. The range of current going through glow plugs on Delica L300 (1991 - 1993) is (80A to 40A). If you measure the current going through Hyundai glow plugs on the same model year, the range is (60A to 40A). This means, the glow plug warm up time is much slower than 6.2V ones.
However, the most important thing is that there is no overheating problem. Hyundai ones have 'built-in resistor' (variable resistance versus engine temperature) to prevent overheating.
We don’t carry 6.2V and do not want to sell anyway as all aftermarket ones are really bad ( Only Mitsubishi OEM GPs are only exclusive solution ).
But unfortunately Hyundai never had 6.2V system in their 4D56 diesel engines ( porter, starex, Libero, Grace, Galloper ), because they knew all defects for Mitsubishi 6,2 V system when they made 4D56 diesels in Korea.
- cost of hardware?
- can it be installed by someone handy with a soldering iron?
** Unfornately we do not sell hardware ( ECU ) itself as we need to modify/install in current 6.2V system.
Our new system does not disturb 6.2V ECU anyway as we strongly believe it has something to do with other functions in early models ( still studying ).
Our total price has fluctuated ( $299-$499, except set of glow plugs ) depending on the season, promotion, what part we need, etc.
Usually we consider replacing 1 pin sensor, 2 pin sensor, relay in addition to replacement ECU.
It takes appro. 3 hours to finish.
We install it only at my shop.
- does it require a specific glow plug or are there several it will operate properly with?
** I don’t know the price/quality of any other glow plugs sold by other importers here.
But I used to use some brands before importing Hyundai 11V GPs ( 3 years back ).
But I was disappointed with those products all the time.
Our first delica with Hyundai 11V GPs installed ( 1993 late model L300 ) is still running with those.
We have lots of testimonials for Hyundai 11V GPs’s efficiency and excellent starting in severe cold area.
Thanks for reading.
Steven
