OEM Alternator Charging troubles? Introducing the Linda Module

Post by JT68 »

Hi Guys, another cool one-of a kind product from DRP:

Linda's Alternator Module.

What is it? It's a self contained regulator circuit for trouble shooting and replacing flaky charging circuits for OEM (roadster only) alternators.
All years- Late 65-70 (negative ground) only.

Why is it called Linda's Module? A couple years ago, Linda went through a nightmare trying to self-trouble shoot her oem alternator system. She removed and replaced the alternator and regulator multiple times, bought a new alternator from us, returned it (perfectly good), replaced connectors etc, and I think ultimately determined it was a flaky wiring problem and probably needed a harness. No surprise really, but it gave us the idea for this.

Why the Linda module?

To be brief, you can test and/or fix your charging circuit without even removing your alternator! If your alternator is good, you can have it charging and properly regulated in 5-minutes. Basically, it replaces the entire regulator system and wiring other than the alternator and the large white power lead. --Just pull the 4-pin connector and plug in "Linda". If your alternator is good and your 30Amp(large white)power line is powered, you will be charging.

If not, your alternator is dead.

R&R of the left hand 68-70 alternators is not much fun. So now you don't have to remove it and can test it on the car independent of the rest of the circuit. Right hand cars are easier, but the same applies.

Linda is also a solid state, adjustable regulator with "stand-alone" connections. If you install it permanently, it will replace your entire OEM regulator and regulator wiring. If you just connect the 4-pin connection, (no mounting required) the alternator should charge.

If your charging circuit was hacked by #$%@&* clueless PO, no worries, plug in Linda and you are done.

For 311 members only, we'll even offer the Linda module for rent. Buy it, use it, keep it if you like, or return it undamaged and we'll deduct 40$ rental. You can save HOURS of troubleshooting hassle.

It's also a great tool if you service or troubleshoot roadsters frequently. (We are sending one to Mike Young now) Trouble shoot an OEM system in 5-minutes without removing any components.

I use one all the time now to test OEM alternators that we rebuild in-house. (tested two today!)

These are not on the website, just pm, text or email if you need Linda. Best always!

/\ This is awesome. Especially for 68-70 owners, not having to pull the alternator is a huge relief.

Ha, I missed this initial post. :shock: Otherwise occupied.
So cool to have a tool named after my ineptitude…. :wink:
Seriously though, good job JT, making things as simple as possible for those of us who struggle. Have to repeat how helpful and patient you were. And that nice little alternator tucked in on the left side perfectly, getting blamed when it was wiring all along, in the driver footwell. So for those who can’t trace wiring and all that, this is a great option. Hope it is put to good use!

Hi Linda, no ineptitude, you would not believe how common these problems are! Sometimes these old charging systems just refuse to cooperate, often act up intermittently, and give even experienced automotive electricians/shops a very difficult time.

We just wanted to come up with a simple way to help folks find a correct diagnosis. A few months after your experience, we had another customer up north spend a fortune paying a shop by the hour. They went through the typical steps, pulled the left hand (not fun) alternator, bought a replacement, installed it, pulled it back out for bench testing(both alternators were good), put one of them back in, bought two regulators(both good), then spent hours jacking up the wiring and connectors- all the time charging this guy by the hour! It was an intermittent regulator wiring problem ultimately.

If they had the LM, there would have been no need to remove, buy and replace the perfectly good Mitsubishi alternator in the first place. The owner could have installed and run the module permanently for about 1/5 of his labor bill alone (and left the original stuff in place for aesthetics) -or-just using it for diagnostics, they would have known it was certainly a regulator/regulator wiring issue in 5 minutes!

After we used the first version a few times for testing LH conversion alternators, we knew they would save hours of frustration.

We don't expect or plan to make much money on these units, but they sure will help many roadster owners!
