Hi,
I did try just using the charging pin on my trailer connector. It worked fine--until I attempted to start the generator and it burned out the relay. Fortunately my cousin had one to replace it.
I'm really looking for a Trik-L-Start type device, that would limit input amperage, while doing just tiny charging on the generator. This would be to allow me to leave the key on, so I can use the Pinella remote.
As to why not use a Trik-l-Start? Well they cost about $120 USD in Canada, plus shipping. And because they are over the "limit" I then get to pay GST and PST on top of the $120. Now the cost is approaching $180 bucks Cdn plus shipping! * ouch *
:h
Something does not add up.
Your using a 7-10Ahr battery to start a generator? Right?
Burned out a 30A, possibly 40A tow charging relay in the process starting the gen?
Gen is pulling more than 30A-40A when starting, 7Ahr-10Ahr AGM isn't going to take that for long which is why relay burned..
Your trying to get around this by using a DC-DC charger?
Right?
Yeah, I don't see that working so well, most likely will be burning out the DC-DC unit in a hurry, they are not designed for that kind of overloads..
You would need a switching DC-DC power supply which has a current limiting fold back.
You need to re-evaluate, check the starter amps being drawn, resize the gen battery, need a bigger gen battery that can support the starter cranking amps, then you won't be burning up relays or fuses in the process.
The battery source which has significantly more voltage and Ahr capacity will not sag and the gen will pull more current from the battery which can support the current.
Even my backup gen I have for my home, I use a 5A multistage charger to keep the battery up to full charge at all times..
I NEVER attempt to start the gen for testing/exercise with the charger powered, always disconnect the 120V from the charger, THEN start the gen.
What you are doing is no different..
